New Yorkers can RSVP for a free event featuring DJ sets from Major Lazer (Diplo + Switch), David Guetta and others, as well as appearances by Dr. Dre and will.i.am. The event, happening tomorrow at 4 p.m. at the Best Buy in Union Square, is one of many “Club Beats” events that will be planned across the US.

Club Beats “is a new in-store destination created in partnership with Monster and Beats by Dr. Dre, founded by legendery artist and producer Dr. Dre and Jimmy Iovine, chairman of Interscope Geffen A&M Records.”

The event also plans to allow visitors to try DJ equipment stocked by Best Buy, as well as some non-DJ equipment called “DJ Hero.”
