When the members of the legendary “Tropicalia” band Os Mutantes took the stage before an audience of thousands at the Hollywood Bowl a few years back, it seemed one of the greatest secrets in modern music was finally out. The seminal band whose ethereal absurdist pop music had inspired so many prominent musicians since their breakup decades before, were back. This time the world seemed ready. Now this influential band has reemerged with a brand new much anticipated album entitled Haih or Amortecedor on Anti-records, their first new album in over three decades. On it Sergio Dias has collaborated with two of the founders of Tropicalia, renowned songwriter and multi instrumentalist Tom Ze and Jorge Ben who wrote the band’s first hit Minha Menina. But don’t expect anything like nostalgia from Haih or Amortecedor. The end result is a record that brilliantly updates the band’s legendary “Tropicalia” sound, propelling it out of the sixties and into an uncharted but undeniably exotic future. As expected, the songs utilize a startling assortment of instrumentation, from austere violins to distorted metallic guitars and something called a crazy flute, lending an underlying theatrical power to their genre defying music. The song “Bagdad Blues,” with its tinkering old piano and seductive horns, conjures an otherworldly cabaret while “Querida Querida” is modern rock music unlike anything you’ve heard before .
