Like other aspiring young musicians, he played with various childhood friends, but began a lifetime habit of joining or "sitting in" with more than one band at a time, learning from the exposure to other differing musical influences and interests.

Initially emerging in the early 80's as musician/engineer in an esoteric rock band/studio collective called Polymorph, Immerglück recorded his first single with a band named Mod-L Society (featuring future Counting Crow Adam Duritz): "Back To Baltimore"/"Janie", in 1985.

The Monks of Doom were a side project formed by members of the popular progressive Bay area indie rock band Camper Van Beethoven.

[4] Original guitarist Chris Molla left the group shortly after the band formed[4] and was replaced by Immerglück, who contributed guitar, pedal steel, vocals, mandolin and keyboards.

[citation needed] In late '94/early '95, on drummer Michael Urbano's recommendation, Immerglück was brought in to record seminal American songwriter John Hiatt's album Walk On.

He has also performed as both a session musician and a sideman with a wide range of other artists, including John Hiatt, Coby Brown, Chantal Kreviazuk, James Maddock, Chris Stills, Tyson Meade, Elan Sara Defan, Cracker, Hootie & the Blowfish, Papa's Culture, Jonathan Segel, The Walkabouts, Johnny Hickman, Low Stars, Jason Karaban, Chris Seefried and Sordid Humor.

In 2016 Immerglück produced and played on flamboyant Indie Rock legend Tyson Meade's forthcoming album Robbing the Nuclear Family, as well as joining bizarre improv collective Mushroom.

They include: Jimi Hendrix, Bob Dylan, David Bowie, Otis Redding, Captain Beefheart & The Magic Band, Can, Grateful Dead, Gang of Four, Peter Green's Fleetwood Mac, Led Zeppelin, Miles Davis, Tangerine Dream, The Rolling Stones, King Crimson, Pentangle, John Coltrane, Muddy Waters, Brian Eno, Tinariwen, and Roy Harper.
