Wazzup Ron, yr musical curiosity is always refreshing! That clip you provided was good but that's how he sounded now. Truth be told, at this point, much like Frank Sinatra in the winter of his career, his voice was barely a shadow of what it was. In his prime that voice was SO special. He was an absolute killa when it came to the salsa/dance tunes but when he slowed it down is when his instrument truly sang! A beautifully sensuous velvet tone, perfect phrasing, always in tune. Had that old skool type of class as a performer, always a gentleman.
In 1971, after coming out of rehab for heroin addiction, he recorded his 1st solo record after recording hits with Joe Cuba and Eddie Palmieri. His bandmates donated their services and recorded a classic. Anacaona, the video shown before, is actually a tune from this album. The trick to listening to songs sung in other languages, is to simply listen to the vocals as if they're instruments playing solos. It's especially easy for jazz lovers accustomed to scat singing. I do it all the time when listening to Brazilian music. Here's one from that record, simply called 'Cheo', recorded in 1971.
'Mi Triste Problema' (My Sad Problem)
