Blair Underwood : The Joe D Show Episode 19

If you wanna bump it, bump it with a trumpet.

Blair Underwood does that — in a way — in “Paradise Blue” at the Williamstown Theatre Festival, where he makes his debut on Wednesday.

Underwood, known for “L.A. Law” and “A Streetcar Named Desire” on Broadway, plays an embattled trumpet player in the drama by Dominique Morisseau (“Detroit ’67”). The show runs July 22-Aug. 2. Details at wtfestival.org.

He talks about trumpet lessons, composers Kenny Rampton and Bill Sims Jr. who've written music for the show and running into ex-“Sex and the City” flame Cynthia Nixon, who’s working on another play at the annual fest.
