Morgan Pettersson played drums in Swedish crossover-metal act B-Thong. He replaced original drummer Staffan Johansson in 1993.
Nowadays he plays drums in traditional heavy metal band Ram. The group also features bassist Leif Larsson (ex-Frozen Eyes), guitarists Harry Granroth and Daniel Johansson, and Oscar Carlquist as lead vocalist.
The musicians describe their sound as "a blend of Judas Priest, Black Sabbath and Iron Maiden, but with a strong original feel throughout all of the material."
The band released their debut EP, "Sudden Impact", in September 2003 through their web site, www.ram-metal.com. Ram's full-length debut, "Forced Entry", saw the light of day in November 2005.
