Galaxy practice, making demo tape for Java Jazz

Last Sunday, after doing the fitness activity, I went to the Yamaha building and had the jazz band practice. For the beginning part of the practice, we were making a demo tape for a big jazz festival in Jakarta called Java Jazz. It is like a tape for the audition. So if the Java Jazz committee accept us or like our performance, then we could perform for the festival, which is going to occur on March 5, 6 & 7.
