Gamma Ray. Never been a big fan of Slayer, even though they have some good songs. But Gamma Ray has that album that I can't remember the name of, and did a Pet Shop Boys cover on that other album that I can't remember the name of. Not that I'm a Pet Shop Boys fan or anything, but I love it when bands do covers of songs of completely different genres, like when In Flames did a cover of Depeche Mode's "Everything Counts".
