The band would morph into Edwin Dare with the addition of bassist Kevin Chown and release three albums between 1992 and 1998 and build a strong fan base around parts of the Midwest through extensive touring.

There he crossed paths with MSG drummer Shane Gaalaas and bassist Barry Sparks, with whom he formed the all-instrumental progressive rock trio, Cosmosquad.

[9] In 2003, after a UK tour with $ign of 4, Kollman began working with bassist/vocalist Glenn Hughes (of Deep Purple fame) and drummer Robin DiMaggio in a short-lived, pop-oriented trio named Shape 68.

[13] That same year, Kollman, Red Hot Chili Peppers drummer Chad Smith and keyboardist Ed Roth, who had met playing with Glenn Hughes, formed an all-instrumental band inspired by their shared love of 70s funk rock and fusion.

Still unnamed at the time, the group, rounded out by Kollman's former Edwin Dare bandmate Kevin Chown on bass, debuted at the 2008 NAMM Show in Anaheim, California.

[15] Kollman would team up with Glenn Hughes for a tour of Europe in 2009, documented via the Live In Wolverhampton 2-CD and DVD release, recorded over the course of two nights, June 6 and 7, in the singer's hometown of Bilston, England.

[23] In February 2014, Kollman filled in for guitarist Marc Bonilla with California Transit Authority (CTA), led by legendary founding member and drummer of Chicago, Danny Seraphine, for a handful of U.S. East Coast shows.

Later that same month he would join old friend Mark Mikel on the inaugural Progressive Nation at Sea cruise, masterminded by former Dream Theater drummer Mike Portnoy.

[24] Released on YouTube in March 2014, Kollman collaborated with fusion trio 107и on a cover of Bill Bruford's "Beelzebub" off his 1978 solo album, Feels Good to Me.

[27] The aforementioned "Seasons Will Change" would re-surface in early 2018 as part of the eponymous debut album by Dukes Of The Orient, spearheaded by John Payne and keyboardist Erik Norlander.

[30] Kollman would also surface in yet another progressive rock project, Artifact, alongside vocalist Jeff Scott Soto, drummer Joel Taylor, flutist/saxophonist Gary Meek, bassist Eugene Sharikov, and keyboardist Edward Tsiselsky whose debut single Life Is Good[31] was issued in October 2016; the band's full-length debut, also titled Life Is Good, surfaced in August 2017 under the name RTfact.

Kollman, Taylor and Meek had also taken part in recording the yet-to-be-released Vision of Sound - The King Crimson Story tribute album, a Russian-American collaborate effort spearheaded by Sharikov and keyboardist Dmitry Ilugdin.

[36] On March 18, 2021, Kollman released the song "Superstring Theory"[37] as a digital single on his Bandcamp site and announced a May 21 release date for his sixth instrumental solo album, East of Heaven, with contributions from long time collaborators Shane Gaalaas and Jono Brown on drums, Cirque du Soleil music director, Paul Shihadeh, on bass, and his Eikichi Yazawa band mate, Guy Allison, on keyboards.

The line-up would include Shane Gaalaas and Steve Jenkins on drums and bass, respectively, as well as special guests such as Red Hot Chili Peppers and Bombastic Meatbats drummer, Chad Smith.
