Bukowski Night at Deer Pile (Tuesday) Celebrate the writing of Charles Bukowski this evening with a slew of tributes to the booze-loving, lowlife poet. The night will begin with readings by Daniel Landes and Westword's own Josiah Hesse, and continue with musical adaptations of the work by Lizzy Allen. Following the readings, you can see the man himself on film in a screening of the doc Bukowski: Born Into This, and then watch the semi-autobiographical, Bukowski-penned film Barfly.
