Eric Wagner was a founding member and long time singer for the Chicago-based doom metal band Trouble (5)
. He quit the group in 1995 after the release of "Plastic Green Head" (the group dissolved a short while later) but rejoined in 2004. Eric quit again in May of 2008, citing a dislike of touring. In 2012, Eric formed the bands Blackfinger (2)
and The Skull (4)
(the latter formed with former Trouble members Ron Holzner and Jeff Olson).
