A drab stretch of land underneath McGrath Highway became a futuristic dance floor Saturday night when Project MUM: Somerville’s Final Frontier moved into orbit. The intergalactic dance odyssey, part of the Somerville Arts Council’s ArtsUnion series, featured four hours of music spun by a team of DJs led by DJs Flack, Yamin, Axel Foley & Pace. Dancers grooved all night under lighting by illuminist Todd Sargent and special visual effects by by VJ Dziga.
