That's awesome. Do Carl-Marie Widor's (pronounced Vee-door) Toccata in D. (Organ symphony no. 5, op 42 no.1) It's long, but you should do it. I've heard the low organ pedal bass notes played by trombone, along with the organ, and it's banging. You would be a legend if you arranged it and performed it with a bunch of trombone tracks like you did here. Pleeeeeease. I actually thought about doing it on kazoo but my voice is trashed from smoking and I don't have the technical know- how. The musical know-how, yes, but I don't know crap about recording and producing multiple tracks like this, although I'm sure there's no shortage of know-it- alls who would tell everyone how easy it is. I'm sure it is, but not for me. Anyway, DO IT!!!! I'll search for it on about a year. Thanks.
