Go back in time to the heady days of rap's infancy in 1980s New York with Krush Groove. The 1985 film is a slightly fictionalized account of Russell Simmons and Rick Rubin's rise to fame via Def Jam Recordings. Blair Underwood plays Russell and Rick Rubin plays himself (and not too believably, either) — two street-wise college students who manage Run-D.M.C., Kurtis Blow and the Fat Boys. While they're trying to make it big and bring rap to the world outside the Big Apple, Russell is also competing with his brother, Run (of Run-D.M.C., naturally) for the affections of Sheila E. (played by herself). Keep your eyes open for LL Kool J and the incredibly young Beastie Boys. The Webster Film Series presents Krush Groove as part of its Strange Brew series at 8 p.m. tonight at Schlafly Bottleworks (7260 Southwest Avenue, Maplewood; www.webster.edu/film-series). Admission is $5.
