Now for a real story...
I was practicing in this strange basement beneath a print shop for about a year. BACKMASK was sharing the spot with a blues artist who occasionally lived there when he fell on "hard times." He told us when we moved in that he felt a presence in there when he was by himself playing guitar late at night.
Well, for a few months, BACKMASK started a (misguided) recording project in there, with my iBook and MOTU 828, and some ghetto mics. We were tracking drums (very badly) and every time I'd go back to my 828, the knobs would be twisted in different positions (that I didn't put them in.) This later started happening with the knobs on my Flextone II head. There was also a strange power problem in this building, without Furman line regulators, virtually nothing worked properly, even some analog stuff.
Eventually my drummer started noticing a strange dampness forming above his drum set on the roof, and he had repeat visions out of the corner of his eye of somebody hanging themselves above the drumset.
We'd freak ourselves out pretty well during the late nights, and the blues guitarist had put a life size cardboard cutout of a Stormtrooper from Star Wars in the bathroom. One night we had the lights extra dim for a "vibe" during practice. I got so freaked out about the ghost that night, that I ended up kicking the Stormtrooper because I thought it was the ghost.
I'm happy to not be practicing there anymore, but the ghost was at least mostly of the friendly/prankster variety. Our recordings from that spot sound horrendous.
