Mercy was a Swedish NWOBHM doom band whose claim to fame was that it featured Messiah Marcolin (an Italian), later of Candlemass, at one point. The group was formed in 1980 and issued a demo in 1981. The band was lead by Andrija Veljaca (a yugoslav) and essentially became his solo band. Messiah actually joined on the full-length debut at the age of 16, which was inclined towards NWOBHM, but the band had a 1982 EP called Swedish Metal. The EP featured Christian Karlsson on bass and Paul Gustavsson on drums. The debut full-length presented Magnus Klintö on guitar as well. It was Messiah and Andrija with bassist Jorgen Horst for Witchburner, which took on a doom direction. At this stage Messiah began wearing inverted crosses on his face.
Nuclear War Now! issued a 2007 single of the band called Session 1981 which was previously on the TPL re-release of Swedish Metal and Mercy.
Andrija Veljaca had died in August of 2005 reportedly from cerebral haemorrhage. The man had songs in the can at the time.
