Diki I imagine it's the same feeling you get when you go out and gig, put on your best performance and nobody claps....I expect we've all had a few of those eh!
I played in a club once where the artist the night before was so bad they were still booing when I went on the next day!
Sadly we here in the UK do not have the gigging oppurtunities you have due to bad UK economy and the dreaded disco killing live music, I personally have only had 7 gigs in 6 months but at least I have plenty of practice time.
