Swizz Beatz's performance at an event in New York this week (ends20Jan13) went up in smoke when a speaker exploded during his set.

Alicia Keys' producer husband was performing with rapper Waka Flocka Flame during the Vh1 Save the Music Foundation's Songwriters Music Series at the Hard Rock Cafe in Manhattan when smoke began billowing from an amp on stage.

The pair stopped the show, and a technician ran on to fix the problem, as Beatz joked to the crowd that the stagehand was "literally saving the music", according to New York Post gossip column Page Six.

Once the speaker was fixed, the pair continued with the gig. The event raised funds for victims of superstorm Sandy and other performers included Busta Rhymes and Sean Paul.
