Cuban ensemble who some have compared to Jethro Tull. They certainly have a fine flute player and play some heavy riffs so I guess I see the comparison but these guys are serious proggers. There could be some parallels with Japan's Kenso, too.
All comparisons aside these guys can really play! This is a collection of tracks recorded as the title suggests, between 1993 and 1995. Rescued from complete obscurity by the prog labels Luna Negra (Mexico) and Musea (France) this CD is the only readily available release from this fine band.
