For rehearsals and stuff, we just go with a Zoom H2. We did one show at a local concert theatre with a great sound system where I brought my recording rig out and took a bunch of taps off the main board and did a live recording. Each channel was recorded to a separate track, so I could bring it home and mix it at my leisure. It turned out quite well. Results are on our website at www.now-here-this.com. They're in the mp3 player with anything tagged "live at the westside."

Could I get some more talent in the monitors, please?

I know it sounds crazy, but try to learn to inhale your voice. www.thebelcantotechnique.com

Chris is the king of relating music things to other objects in real life.
I just played a gig at a larger local venue, and the sound guy basically offered to record it directly off the soundboard. It sounded pretty good, so I plan on doind that from now on. It never hurts to hear what the audience heard
Yeah. A guy I play with has a really nice PA (http://pro-audio.musiciansfriend.com/product/Yamaha-Yamaha-EMX5016CF-S115V-PA-Package-with-Monitors?sku=482671). I run a line out into an audio interface (http://pro-audio.musiciansfriend.com/product/MAudio-FastTrack-Ultra-USB-2.0-Audio-Interface?sku=241806) and then record with ProTools on my laptop.

What exactly are you wanting to know?
yeah we do, but not just audio--we video tape all of our gigs to see where the performance can improve.
Yeah, occassionally I'll get someone to videotape the gig or practice. Primarily it's to see whether we're entertaining to watch or not. If not, take note of why and work on fixing it.
And no, Guitar Hero will not help. Even on expert. Really.
My first gig was video taped by the drummers gf, I found out I look a hell of a lot cooler headbanging or even making an idiot out of myself then just stand playing.
