I had Slayed and the red live album on cassette when I was a kid but they never really did it for me and once I heard Piledriver it was all over for me. For Brit boogie the early Vertigo Quo albums are hard to beat.
And bringing it full circle Piledriver was my introduction to The Doors via Francis Rossi's well disguised love of Baudelaire, Rimbaud and Blake .....
.... acutally it was their cover of Roadhouse Blues
