The band in question is a mix of a jazz rock and funk with Latin influences. Very little information about that one but I assume it was formed in Zürich in 1969, as stated on Rateyourmusic.
Highly energetic jazz-rock with an occasional \"horn mode\". It's true that the heart of the band lays with the drummer, their's is an exellent one, providing some really creative percussive support to lift the band to higher grounds. The album itself is a mix of semi-commercial and more progressive ideas, really diverse and interesting.
