For a minute, there, I thought that was Jim and he looked like he gained a lot of weight and grew a rather long beard. That was a pretty nice video and it actually kept my attention all the way through.
I really liked the Paganini piece. Great tone. Played with restraint. Played with dynamics. The only thing I disliked was that I could hear the keys clicking.
I'm on the record for saying that if there's nothing else you want to play and it's alto clarinet or nothing, please play the alto clarinet. I really don't care too much what you play as long as it gets you interested in music. However, I'm still unconvinced that an alto clarinet is the best "tenor clarinet" choice. What about the basset horn in F?
