One of the best surprises of last December's Winter Elixir concert was the special cameo appearance during Dave 1 of Chromeo's set by A-Trak, who performed a killer version of Duck Sauce's hit track, "Barbra Streisand." I guess we shouldn't have been too surprised, though: Dave 1 and A-Trak are real-life brothers after all. Now A-Trak is headlining his own show at Terminal 5, and pre-sale tickets for the BroBible-presented April 30 concert go on sale Friday at noon. Joining the Montreal-born DJ on the bill are The Clipse, Kid Scissors, and Gaslamp Killers. It's going to be an amazing show and we want to make sure you're all there.

The pre-sale on Ticketmaster begins at noon tomorrow; we'll post a reminder then, with a link, but we just wanted to officially announce the concert. Here are all the details:
