This is a compilation Los Shakers decided to do in 1965 exclusively for the US-market.
It never really made an impact over there, but what makes this album outstanding, is the different recording session they used for this compilation.
Production is very sloppy (compared to the original singles and LPs in Uruguay), and the band plays with a much more garage overall feel to it.
Since the quality is so shitty I remastered the originally 12" recording for 1PocodMusica.
