Kosche was in Jovian Storm, he fronted the band Steep, and became the lead guitarist for the rock band Collective Soul.
In 2007, Joel played guitar on Steve Walsh's solo tracks Dark Day and Faule dr Roane. The tracks were released by MusicAndVideo.TV/Brandon Productions
A year later those two tracks appeared on Prog Rock Records re-release of Steve's Shadowman album as two bonus tracks. http://www.therecordlabel.net/progressive-rock/steve-walsh/
