Album: Os Mutantes, Haih or Amortecedor, (Anti)

Formed in Brazil in 1966, Os Mutantes combined pyschedelic rock with traditional Brazilian music to create a sound that has since found favour with artists as varied and influential as Beck, Byrne, Banhart and Kurt Cobain. But can the legend survive a new record, OM's first in 35 years?

Well, time may have caught up with the band's kitchen-sink kaleidoscopia, but Haih still sounds of both the past and the future. The shock factor may have gone, but the musical vision remains thrilling.
