I ran a quick search and came across nothing of the sort on this forum, so here goes. This is a thread in which anybody can post a recording of themselves.
If you have a recording, upload it to a file host (I love Box.net) and let everybody else here and comment!
I have a few things right now, including piano recordings and brass choir, but here's my clarinet multi-tracks I recorded yesterday. First, a short clarinet duet I ran across here on 8notes.com and decided to record. The other is a Clementi piano sonatina (Op.36, No.3). I played it as a clarinet quartet (3 Bb clarinets, and one doubling alto and bass). It came out pretty well - I'm starting to notice my bad counting habits and intonation problems here and there. My clarinets all need repadded ... badly, but I won't use that as an excuse - a lot of slurred scale passages crossing the break didn't speak. I also noticed I use WAY too much tongue. I squeak more when I use the more just the tip - maybe it's just that I haven't practiced clarinet in 3 years, but I have to work on that. Cheers and comments appreciated!
My next mission - a Kuhlau piano sonatina, once I scratch up on my rapid scale up to Bb clarinet's high high C. Yes, that one. I don't think I've ever been able to PLAY it in my life - I can play the same (written) note on alto and bass though, thanks to the vented keys.

Edit: two notes I forgot: for bass clarinet I'm using an alto clarinet mouthpiece because I don't have a bass clarinet mouthpiece right now. Also, when I converted to mp3, it seems that I lost a bit of the bass sound, it went a bit treble heavy on me, so sorry about that.
