I don't know where I've been all this time, but I only just recently discovered the excellent catalogue of hybrid multi-channel jazz SACDs offered by the Concord label. http://www.elusivedisc.com/products.asp?dept=779 I picked up titles by Poncho Sanchez, Cal Tjader, and Tito Puente (can ya tell I like Latin jazz?). I have my eye now on the Art Blakey, the other Sanchez, and the Mango Santamaria discs. And I had already gotten the Chick Corea a while ago. This type of music and sound quality is the reason I got into high-res. The multi-channel mixes are aggressive- purists need not apply. On the Sanchez disc, timbales are almost exclusively on the rears. With Sanchez' and sometimes guest Santamaria's congas up front, the result is sweet. Meanwhile, the stereo tracks are solid, too. They also have some contemporary and vocal music, which I may explore after getting the other stuff I want more.
