Eric Wagner (born April 24, 1959) is an American heavy metal singer who is best known for his work with doom metal band Trouble, which he formed in 1979 when he was 20 years old. He briefly left Trouble in the mid-nineties and formed Lid with guitarist Danny Cavanagh, resulting in 1997's In The Mushroom. Wagner rejoined Trouble in 2000, after his replacement Kyle Thomas was dismissed from the band. He appeared on Dave Grohl's heavy metal side project Probot in 2004.
On May 2, 2008 it was announced via the official Trouble website that Wagner had left the band again because "at this moment in time I just can't handle touring anymore." His replacement was named as ex-Warrior Soul frontman Kory Clarke.
Most recently, Wagner has been recording under the band name Blackfinger. He also recently formed The Skull, a spin-off band featuring two other former members of Trouble, bassist Ron Holzner and drummer Jeff "Oly" Olson.
