solid 70s session from Willie Colon -- a combination of a few tracks from previous efforts, mixed with other new ones, all featuring lead vocals by the wonderful Hector Lavoe! The work on the album's the kind that was so influential at the time, it's almost hard to hear how important it was from this angle -- because Willie's working in a tight, hard style that so many other groups copped afterward -- yet this one's still the original, and a good solid listen will remind you of the power in these grooves! Tracks include the groovy "Ah Ah/O-No", "La Banda", "Ghana'e", "Pirana", and "Abuelita"
