Metropolis, aka Providence’s singular “Psycho-Electro-Acoustic-Islamo-Judaic-Hindu-Afro-Dance-Surf-FreeJazz-Metal-Groove Music” superstars, are playing their final performance EVER tonight at Tazza on Westminster St. Some of the band will be departing for the summer so if the concept lives on, it will at least have to be constituted from a different lineup. This is can’t miss shit.
