Hi sir,
Nice site indeed! I'll share this site I'm also using now. smartmusic.com. Access to hundreds of accompaniments for solos for all instruments, jazz band play-along and improvisation exercises is only $30 per year. I find it really useful for play-for-fun musicians like me. Try it. It's a package of practice tools.
SmartMusic is award-winning learning software with the power to transform music learning. Students of all ages and skill levels can play or sing with professional accompaniments, making practice both rewarding and fun. An affordable subscription to SmartMusic gives students the opportunity to explore a wide variety of music from the world’s largest accompaniment library featuring thousands of titles for band and orchestra, solo contest repertoire, popular method books, jazz, and skill-building exercises.
BTW, Sir Ding, Thanks again for the books, they also are very useful.
CHEERS! Tell me how it went.
