When it became clear he had a genuine chance of realizing his dream, Deisinger quit his apprenticeship as an electrician to devote himself to music full-time.
[1] Deisinger joined German hard rock band as a bassist Cacumen in 1985, which would change its name to Bonfire in May 1986 in the interest of having a catchier moniker to push their new album, Don't Touch the Light.
[2] During his time with the band touring Europe extensively with acts such as Victory, Krokus, ZZ Top and Judas Priest.
In December of that year, the last minute cancellation of a planned Christmas vacation to Koh Phi Phi Don ultimately saved Deisinger's life; the tsunami that decimated parts of Thailand, Indonesia, India, Sri Lanka and Malaysia on 26 December 2004 laid waste to the resort where he was supposed to be staying.
[3] In 2005 Deisinger approached Canadian music journalist and writer Carl Begai about co-writing his memoirs, which focused on his Bonfire career.
