If you've heard of the above recordings you will know that they are very difficult to get hold of. If you don't know about them, then its time to learn. These are recordings made by groups of the best players from the US in the 50's/60's. What you end up with is superb playing with soloists trying to out do each other. The arrangements are great. The good news is that these have been released on 1 CD by AVID www.avidgroup.co.uk. I've been waiting for 15years to get an orginal copy to replace my (very) worn tape. I ordered on Monday and it arrived this morning.
