what a riff

Damn, nice find. That predates Cirith Ungol's first album by a decade. I didn't think anyone was doing music this hard that long ago. Although a slightly different vein, Uriah Heep released the disc with 'Stealin' in '73, and that was the earliest, hardest rock that I knew of. Even Budgie, who released their first disc in '71, took until '74 to get really weird with songs like 'Crash Course in Brain Surgery'.

Nice submission Lurchi! I am impressed.
