Well they had a virtuoso drummer, the fastest guitarist in the world, and the highest male vocalist in rock probably ever to this day (makes King Diamond sound like a tenor!). Apparently the bassist TJ Racer was pretty good too.
Shame about the songwriting... heheh. Nah I have their first album on vinyl and half of the songs are really good (but takes a fair bit of getting used to the style!), the other half REALLY need to be taken back a step. I mean there's a couple of tracks where you have almost black metal blasting, with lightning quick shredding, and vocals reaching the top end of the 6th octave... yet its all got a party/glam attitude! WEIRD MIX! The slower songs like Freight Train, Double Trouble, Long Way From Home, Nasty Reputation, Shot Heard Around The World and O.F.R. are great though! (After a while haha)
It's very very extreme.
