„... Heinz Geisser is nothing less than “omnidirectional.“: Chris Kelsey, New York City
„... His style is complex, multi-layered, subtle, and telepathically attuned to timbral contrasts.“: Bill Barton, Signal to Noise
„... drummer Heinz Geisser provides the kind of swirling thunder and lightning that make a distinctive impression on any audience.“: Jim Santella, All About Jazz
„... Geisser is a good listen, with a light touch but razor-sharp reflexes and a devilish facility on the cymbals.“: Will Montgomery, The Wire
„... Geisser pounds out a constant flood of polyrhythms…“: Derek Taylor, Cadence Magazine
„... Heinz Geisser is terrific on percussion throughout. His solo on the title piece is a lesson in shading, timbre, and phrasing, as he avoids cliché and instead focuses on sound.“: Steven Loewy, All Music Guide
„... Heinz Geisser most certainly is a virtuoso. His ability to imply multiple tempi (thereby feeding the other players the widest possible range of rhythmic options), his timbral prescience, and his manifest intensity place him on a level with the best free drummers.“: Chris Kelsey, One Final Note
„... the incredible Swiss drummer Heinz Geisser.“: Village Voice New York City
„... Geisser is as thrillingly unpredictable as Randy Peterson…“: Fred Grand, Rubberneck
„... Geisser, for his part is a sound colorist in the great tradition of Bennink, Oxley, Lovens and the rest.“: Robert Spencer, Cadence Magazine
„... Geisser’s debt to Elvin Jones is evident in the short, dramatic gestures he combines into a swirling maelstrom.“: James Hole, Coda Magazine
„... Geisser masterfully balances sensivity to group dynamics with a forceful, propulsive, free rhythmic energy; prodding and buffeting the improvisations along their extended trajectories.“: Michael Rosenstein, Cadence Magazine
„... Heinz Geisser may be best known as the founder and percussionist of the Collective 4tet […] the 4tet is an extraordinary band, much of its character coming from Geisser’s drumming, which has a remarkable combination of density and transparency, an ability to comment and color, to suggest and direct, that demonstrates the subtle contrapuntal intelligence of the finest improvising drummers.“: Stuart Broomer, liner notes to album “Toni’s Delight“
„... Geisser’s superb drumming is marked by a delicious sensitivity to timbre.“: Larry Nai, Cadence Magazine
„... Heinz Geisser’s drumming is dense and fast, providing thick crosshatches of percussive shading to the other musicians.“: Douglas Wolk, CMJ New Music Report
„... Geisser is a power drummer who constructs a massive undercurrent of energy that magnifies the amount of electrical voltage shooting through the session.“: Frank Rubolino, One Final Note
„... Geisser contributes the spatter and drip of near liquid cymbal timbres.“: Ken Waxman, ALL ABOUT Jazz Los Angeles
„... Geisser is a fleet post-Elvin drummer…“: Ben Watson, Hi Fi News
„... Geisser’s sharp and decisive drumming creates a drive that livens up the music.“: Toyoki Okajima, Jazz Hihyo Tokyo
„... Geisser has an interesting way of breaking up lines and varying the momentum of the improvising quite a lot.“: Jason Bivins, Cadence Magazine
„... Perhaps it’s Geissers’ probing , provoking drums that first suggest the potential for release and catharsis.“: Duncan Heining, Jazzwise
„... The Collective 4tet’s work is multilayered yet not too dense, with an overall airiness absent from most Improv sessions, thanks to the often jubilant momentum provided by the crisp drumming of Heinz Geisser…“: Barry Witherden, THE WIRE
„... You can tell that bassist Parker and drummer Geisser have been playing together for quite a while as they work splendidly together, moving together and weaving their wares superbly.“: Bruce Gallanter, Downtown Music Gallery NYC
„... Of course, also Heinz Geisser plays an important role here, although the language of this drummer is much more rooted in the free-jazz tradition. He appears to follow the formal visions of Mazzola, to read and emphasise their dramatic dimension. He shows great skill in preparing and underscoring the points of culmination by varying the density of the movement and sound. Geisser also adds tons of strictly jazzy, ecstatic vitality to the intellectual structures built by his partner.“.: Michal Mendyk, Polskie Radio (transl. from Polish)
„... and Geisser’s almost elemental drumming.“: Nate Dorward, Cadence Magazine
„... Nulle “réplique“: Heinz Geisser est percussioniste par quatre chemins.“: Alexandre Pierrepont, Impro Jazz France
„... Heinz Geisser si conferma percussionista di sensibilità spaziale acutisssima e di tecnica superiore. Plastico como Andrew Cyrille ed economico come Hamid Drake, fa apparire critico ogni suo sorgere.“: Giuseppe dalla Bona, Musica Jazz
„... Heinz Geisser è un percussionista che riesce a mettere in risonanza infinite sfumature timbriche.“: Gianpaolo Chiriacò, JAZZIT
„... il drumming di Geisser e le pulsazioni di Parker fungono da collante insostituibile…“: Piercarlo Poggio, Blow Up
„... Il percussionismo intelligente del leader funge da perfetto elemto coagulante, caratterizzato da una concezione del ritmo che alterna momenti di ‘’pieno magmatico’’ ad altri diradati, scarni, non invadenti, dominati da un battito in punta di piedi.“: Enzo Pavoni, Audio Review
„... La trama percussiva di Geisser è un guazzabuglio inestricabile…“: Vincenzo Roggero, All About Jazz Italy
„... Heinz Geisser è un percussionista incredibile per tutto quello che sa tirare fuori dal strumento.“: Vittorio LoConte, All About Jazz Italy
„... une percussion aux aguets au poids précisément évalué, maîtrisant les flux.“: Philippe Alen, Impro Jazz France
„... Geisser et Parker, refusant d’imposer un rhythme castrateur, se laissent porter par le flot dense des possibles.“: “Grisli“, Infratunes
„Le batteur, Heinz Geisser […] est vraiment remarquable par son écoute et la diversité complexe de ses frappes et de leurs enchâinements: on peut se concentrer sur son jeu a l’écoute au casque: un régal.“: Jean-Michel Van Schouwburg
„... Heinz Geisser schliesslich, der Perkussionist ist vielleicht der subtilste seines Fachs in Europa.“: Ulrich Vanek, Jazzpodium
„... Der studierte Gitarrist und versatile Polyrhythmiker, der mit seinem Collective 4tet schon etliche Free-Jazz Aufnahmen von Rang vorgelegt hat, ist diesmal mit seinem japanischen Kollegen Shiro Onuma zu hören…..Hier wird getrommelt, dass die Fetzen fliegen.“: Manfred Papst, NZZ am Sonntag

„Der 1961 geborene Musiker studierte zuerst Klassische Gitarre und Klassische Perkussion. In den 1990er-Jahren dann konzentrierte sich Geisser aufs Schlagzeug und die improvisierte Musik und entwickelte dabei eine hinreissende Meisterschaft.“: Udo Andris, Jazzpodium
„... Geisser’s compelling free-form drumming poses a holistic backdrop. Even when he’s providing subtle asymmetrical accompaniment, he manages to devise subliminal beats that are regimented and deceptively complex.“: Glenn Astarita, All About Jazz
„... Heinz Geisser, batterista e compositore svizzero appartenente alla schiera più eletta di musicisti europei che dall’esperienza del free jazz hanno distillato un ordine e una sintassi coerenti con le istanze originarie.“: Giuseppe dalla Bona, Musica Jazz
„Geisser is one of the best drummers in post bop music.“: Robert D. Rusch, Cadence Magazine
„a drumming that seems to be in its own world.“: Lynn René Bayley, The Art Music Lounge
„...get acquainted with Geisser’s astonishing sound-world.“: Brian Morton, Jazz Journal
