Rene Bloch: Rene and his pachanga orchestra LP

SO I picked this up yesterday. I was struck by the really cool album cover... there is no credit for the album cover.. anyways the LP is on Capitol Records T-1530 .. must have come out around 1962... Capitol- as I recall- did not have much in the way of latin music.. the full title for the band is "rene and his pachanga orchestra" and the album itself "la pachanga"... the album features a song by johnny pacheco who i guess was just beginning to make his mark.. also some participation from paul lopez on trumpet who co wrote two tracks.. paul lopez has his own website here

I wonder if Willie Bobo or Mongo Santamaria who at times played in Rene Bloch's orchestra played on this? i doubt it as it would seem to be too late for them to be on it.. anyways the music is pretty good and with capitol's normally good standards on packaging and sound...too bad there are no credits for the band! i note bloch played for perez prado and the album was produced by curly walter..in fact right now i'm listening to paul lopez jamming on his solo on "lola catuna"!
