Practicing a concerto

I don't know if anyone here would be interested in this, but here is a new website that could be helpful to many people who hate practicing without an accompaniment:
http://www.soloconcertos.com

Soloconcertos.com is a website that provides computer generated orchestral accompaniments for concertos and other pieces for soloist and orchestra.

Hum interesting I shall have a look... maybe some organ concertos are there too.Thanks for tip......I see it is for solo orchestral instruments
