BTW, in all fairness I think people really should stop using "Elevator Music" as a derogatory, cause to be perfecly honest, I like music that people often refer to as "elevator music" - it's usually Jazz-based, and that's something else I'm getting quite fond of lately.  Now that would be an interesting project, a Jazz-based Metal recording with an industrial atmosphere.

Just might try that and release it on cassette.
