Organist Jim Alfredson and guitarist Joe Gloss originally met at Michigan State University in 1997. Together they co-lead various groups before meeting drummer Randy Marsh in the fall of 2000. His experience and leadership served as the last piece of the puzzle and organissimo was born. In the several years since, organissimo has quickly become one of the premiere organ trios of the greater midwest, eliciting accolades from fans and critics alike.

From the beginning, organissimo has set itself apart from the traditional "jazz" trio by focusing on original material and forging a unique group sound. All three members contribute equally and bring their diverse backgrounds to the group, creating a cohesive, multi-layered whole.

Notable performances include the 2003 Clearwater Jazz Holiday, the 2005 Idlewild Jazz Festival, the 2006 Syracuse Jazz Festival, the 2006 Chicago Jazz Festival, the 2006 Detroit International Jazz Festival, Kenny's Castaways in NYC, opening for John Scofield, The HotHouse in Chicago (the performance was very favorably reviewed in the Chicago Tribune), The Green Mill in Chicago, opening for Karl Denson's Tiny Universe, the famous Baker's Keyboard Lounge in Detroit, and Chris' Jazz in Philadelphia among many others.

"organissimo invigorates the organ trio tradition with fresh takes on the genre... eclectic... classic... inventive..." ~ Bill Milkowski, JazzTimes, Sept. 2006

"Combine Alfredson's knack for choosing just the right color and tone in any given composition with his colleagues' ability to match his gestures, and you have one of the most promising organ trios in jazz."
~ Howard Reich, Chicago Tribune

"Lansing, Michigan based organissimo... somewhat self-deprecatingly refers to itself as a bar band. But the group goes well beyond that as it stretches the boundaries of the traditional organ trio with bits of funk, blues, Latin, groove and New Orleans influences."
~ Ed Trefzger, JazzWeek

"Gloss provides chewy chords and measured melodies as a foil to Alfredson's blistering, extroverted style; running with the current fashion that weds mainstream jazz and jam-band soul, Alfredson plays just recklessly enough, committing tiny acts of arson that keep things hot but don't quite bring the house down around his ears."
~ Neil Tesser, Chicago Reader

"Alfredson handles the organ duties with panache, guitarist Gloss' solos and accompaniment mesh wonderfully and drummer Marsh lays down a red carpet of boogie with veteran authority. There's nothing too complicated about organissimo's approach: It's music that reminds of saxophonist Johnny Griffin's aphorism that jazz is music for people who have decided to feel good in spite of conditions."
~ Mark Stryker, Detroit Free Press

"Organ aficionados should consider [organissimo] a red alert. "
~ Larry Hollis, Cadence Magazine

"organissimo... hits the spot in so many ways. Funky, soulful... Old School... New Attitude... a real modern organ trio sound!"
~ Eric Cohen, Music Director WAER-FM, Syracuse, NY

"[organissimo] returns with its second studio effort, jammed with Hammond B3-laced jazz, blues and pop that's every bit as challenging and award-worthy as the debut CD."
~ John Sinkevics, Grand Rapids Press
