Oh good, I was afraid I misunderstood the title of this thread and it was just gonna be about speed metal bands who were really bad and played all wrong. This topic is much more fun!
When I got Witchfynde's 'Lords of Sin' LP with the bonus EP, I didn't realize that the EP was supposed to be played at 45 rpm. 'Moon Magic' sounded pretty fucking cool at 33 rotations per minute.
And then there was the first pressing of the Witchfinder General Live CD, all of which were pressed with the wrong recording speed; again, sounded kinda like 45 slowed down to 33. I actually kept a copy of that version even long after the corrected CDs were available just b/c I thought it sounded kinda cool at the slower speed
