Query: An extremely important mid-1970s Salsa classic.

This all-time classic album was Conjunto Libre's near-perfect debut with their inspired and swinging cover version of "Lamento Borincano" getting things started off right. I do agree with the other reviewer that this CD reissue's sound quality is by no means great but...this is an extraordinary CD that no self-respecting Libre fan should be without.
