I'm quite a fan of those Sanchez Columbia CDs. OK, some of the tracks seem to be aiming at the MOR market but there is some solid stuff in there as well, particularly when Edsel Gomez is in the lineup. I guess it helps if you are a fan of the Puerto Rican style. Incidentally, I caught Sanchez with Hilton Ruiz at Birdland the night they were recording the Candid 'Live at Birdland'. Not one of Sanchez's better nights, perhaps. There were about 15 of us in the audience and Alan Bates was on the next table !
Remember seeing him on baritone in George Coleman's Octet !
Have to say that the Bobby Watson & Horizon releases of this era (maybe slightly before it) are a standout. The Blue Note releases in particular.
