WPFW 89.3FM staffers and volunteers’ recent declaration of “no confidence” in GM John Hughes is just the latest incident in a long history of off-air squabbles at the station. Unfortunately, that kind of turmoil tends to obscure the notable contributions of WPFW’s DJs. Take Tony Carr, whose program “This is Reggae Music” occupies the Sunday midnight slot. Carr has played island sounds on WPFW’s airwaves on and off since 1979, with short stints at WHFS, WOL-AM, and WHUR. But he didn’t get there easily: Carr had to convince station management that a reggae program would be valuable, and at one point he was even suspended. But he went on to become a regular, playing contemporary roots artists alongside old-timers, ska acts, and balladeers; he now boasts that he regionally broke Maxi Priest, Steel Pulse, and Lucky Dube. Tonight at Crossroads, the Kingston, Jamaica-raised DJ celebrates 32 years on the air with a party featuring some of the area’s finest Caribbean music selectors. Carr used to spin at the now-defunct Kilimanjaro club, but tonight, he leaves the turntables to his pals. Hosted by DJ Papa Wabe, the DJ event includes John Blake of the Caribbean Experience, Andy Mix, Bobby’s Music Machine, and a handful of other talents, all playing music from the ’70s through today.

The celebration begins at 9 p.m. at Crossroads, 4103 Baltimore Ave., Bladensburg. $20. 301-927-1056.
