I onced hung out with/roadied for a husband and wife band. Almost every room, and everything in those rooms was recording/band eqipment. To be honest, it was always alot of fun hanging out there, music was going on almost 24 hours a day. Of course, that was before kids, (day) jobs and responsibilities (shudder) walked into our respective lives. I have very fond memories of laying face up on the floor, next to the dog, unable to move a whole lot, listening to them rehearse.
What was weird was, as the band practiced, if you walked outside, the house was so soundproofed, it was like you just walked into another reality. One that was much too quiet. Soooooo, one usually scurried back into the house, and all that sound. Aint music fun!
