Saxon rules. Cloven Hoof rules. Quartz rules. Elixir rules, but slightly less... There're famous band that rules and obscure bands that rules. There're famous band that sucks and obscure bands that sucks.
About Elixir, I don't consider it a classic, more a high archive... Wheels Of Steel, Strong Arm Of The Law & Denim And Leather are classics, Quartz & Stand Up And Fight are classics, Cloven Hoof (the album) is a classic.
But the best NWOBHM (well, excepting Iron Maiden) was another... Yes
ANGEL WITCH - ANGEL WITCH is a CLASSIC!
(Yeah, I know I'm repetitive)
