I dont know what they are talking about
as much as i mack on sax players for "Playing the sax wrong" they have no right to say somthing is wrong with your sound. or the whole vibrato thing other then like at 3:42 where i heard the vibrato was a little too much you did an awesome job. you have an awesome sound for your set up. I have a selmer soloist and for classical use my c star but for jazz use my metal meyer and still dont get that sound your getting, you sound like a tenor and your playing alto i envy you lol. you did an awesome job. now this makes me want to bust out my sax and practice my jazz, i was at school the other day and russle peterson came (hes the sax proffessor over at some school in like minesota) hes good friends with my my band teacher so he and 2 friends came and they did a tribute to the yellow jackets for us and it was awesome. and yeah i sightread a chart that the jazz band class was working on all i had was the lead sheet and had to transpose which aint hard but then i was told to take a chourus and i hadn;t done that in like 2 months so i was really nervous but yeah :P wow i just started to ramble anyways.
Awesome job keep up the work
