Ricardo Donoso is a composer, percussionist, and electronic musician from Rio de Janeiro who currently resides in Boston. He has participated in a slew of projects over the years, notably playing drums for avant-death metal unit Ehnahre and being one-half of the ever morphing electronic duo Perispirit. Ricardo's musical vocabulary draws as much from contemporary composition and drone as it does from techno and noise.
