Ed Warby (Of course!) (Gorefest, Ayreon, Hail of Bullets)
Simon Phillips (Toto drummer and zillions of other bands/projects, but in heavy metal circles most known for his mind-blowing drumming on Sin After Sin)
Pick Withers (From the first 4 Dire Straits records; his dynamic swing in some of these songs contributed a great deal)
Tony Williams (We've had a few typical non-rock/-metal musicians before. I thought that this iconic drummer would be good to include as well. Widely regarded as one of the most important and influential jazz drummers to come to prominence in the 1960s; also pioneer of the fusion movement (combination of rock, R&B, and jazz) with his group Lifetime.)
Thomen "The Omen" Stauch (Blind Guardian)
Brent Smedley (Alive in Athens!)
Bill Ward (Black Sabbath)
Barriemore Barlow (Jethro Tull, 1971-1980). Absolutely great live drummer. Tull reached heights with this man. John Bonham on Barriemore Barlow: "The greatest Rock Drummer England ever produced".
Ingo Schwichtenberg (Helloween, -1995)
