Motorhead - Overkill (1979)
I feel like I've pissed away 23 years of my life not listening to this album. It's a weird feeling.
This album is proto-thrash, face-meltingly fast and loud for it's time blah blah blah; but it has this old 50's rock n' roll vibe which makes sense, Lemmy is a well-documented aficionado and every interview I have read or seen with him he drops some knowledge about good music.
