Come tomorrow night, Pollen, the  trio of Andy Palmer, Maud Morgan and Ben Hirsch will be releasing their first EP of their brand of politically charged art punk. Youthful and full of urgency, the four song, self-titled EP draws heavily on the influence of proto-punk avant-gardists like The Feelies as much the next generation of indie vanguardists a la Yo La Tengo.  In that tradition, Pollen achieves an impressive blend of humor, rhythm and brevity, pop sensibility and dissonance.   Following the reemerging trend of cassette releases, the new EP will be available on tape tomorrow night at 1401 Astor Place.  Pollen will share the bill with last month's Artist of the Month poll winner Those Howlings.
