Robert-
Lock grooves are vinyl grooves that "lock" the needle in to playing
the groove over and over until you pick it up.
For example:
Lee Renaldo of Sonic Youth released an album called: "From Here To Infinity"
which has a lock groove at the end of each song.
Thus, each song never really ends, conceptually.
Another fabulous lock groove record which comes to mind is RRR 100.
This record marks indie-noise label RRR's 100th release.
It's a 7" containing 100 lock grooves! 50 to a side, by 100 artists.
I know these examples aren't very idm-ish, but I'm unaware of any idm
records with lock grooves..............
