Just thought I should share this video with you. London Brass play the Chicken. To me easily one of the classiest brass ensembles out there. Oren Marshall on tuba and I'd rate him as one of the best players around today. Anyone who has seen him live will surely agree!

I sure didn't notice any foot pedal action controlling those sounds - if that was all mouth generated, WOW! (Even if he had electronic assistance it was very good anyway.)

Sounds like your basic envelope follower to me.
