Jim Alfredson (Lansing, MI) comes from a musical family. His father earned a living as a professional musician for many years and encouraged Jim's talents from a very young age. Some of Jim's earliest memories include pulling on the drawbars of his father's Hammond B3 at the age of four.

Jim began writing his own songs at the age of 8 on a Yamaha organ. A plethora of synthesizers and multitrack machines followed until he came full circle at age 17 and began lusting after the sound of the Hammond organ once again. Jim has immersed himself in the mighty B3 ever since, dedicated to the goal of uncovering new directions within the tradition of the organ trio.

He is also the organist and musical director of the award-winning Root Doctor band, one of Michigan's premier rhythm & blues groups.

Joe Gloss (Lansing, MI) picked up a guitar at the age of 8 to learn bluegrass and never looked back. His musical journey has carried him through many genres before finally settling into jazz in the early 1990s.

Joe is known for his melodic, thoughtful phrasing and almost zen-like calm on stage. His varied musical background makes him adept in almost any style but he found his true musical voice studying jazz and classical guitar.

Joe's strengths, including his beautiful harmonic sense and exquisite writing, are the perfect compliment with the rest of the group, pushing organissimo in new and dramatic directions.

Randy Marsh (Grand Rapids, MI) is known throughout the state as the drummer of choice. His resume is distinguised and long but he has never rested on his well-deserved laurels. With organissimo, Randy has found another outlet for his experience, his endless creativity, and his positive spirituality.

Randy comes from a musical family as well. His father, Arno Marsh, played tenor in Woody Herman's Thundering Herd, Stan Kenton's big band, and in Buddy Rich's band. And he is still a staple of the Las Vegas big band scene after over 50 years. But Randy credits his mother, local jazz singer Mary Lou Marsh, for giving him a deep love of jazz.

Randy has been drumming for almost 40 years and shows no sign of slowing down. Indeed, he is at the peak of his playing with organissimo, bringing fire and intensity as well as his trademark sense of humor.
