In Paradisum, a religious a cappella ensemble from the college on the hill, opened for Der Flay, the basement metal band, Thursday at the Bullfinch.

The pairing was repeated, with different repertoire and band order, Sunday at In Paradisum’s school recital at the campus chapel.

Well, who hasn’t heard hi-falutin’ classical chords and angelic voices as intro music to savage rock shows? This just made that blend more human.

The classical chorale wore the traditional choral cassocks and cottas. So did Flay frontman Master Ratzenberger, who was clearly concerned about how his new collegiate classical pals would relate to his sinister scenester acquaintances. Ratz needn’t have worried. The choir drank the Flaymeisters right under the table.

Tonight: CYO at the Bullfinch… Yes Penguins Fly at Hamilton’s… D’ollaire’s is closed for repairs (we’ll explain sometime)…
