Heather Laura Gray is a Vancouver-based choreographer with a background in theatre and film, and you’ll see all her skills come together in the premiere of the multimedia The Tunnel. You’ll get your first chance to see it on Sunday (April 23) at the Roundhouse Community Arts and Recreation Centre as part of New Works’ Dance Allsorts series. Word has it the artist is transforming the venue’s black-box theatre into a vast void filled with original, dreamlike projections. Dancers struggle in shifting light, trying to find their way out of the dark. Expect dramatic and haunting visual effects and raw yet honed dance: Gray has studied everything from ballet to hip-hop. Enter The Tunnel at 2 p.m.; she offers a free workshop for 30 audience members at 3:15, after the show. It then runs at Théâtre la Seizième’s Studio 16 from next Wednesday to Saturday (April 26 to 29).
