September 8 and 11, 12, 13. It's another blockbuster September at Basilica Hudson, thanks to dates featuring two of the artistically searching multimedia performance center's most cherished returning attractions. Up first is the long-awaited second visit by Montreal's masters of modern, epic, orchestral psychedelic rock, Godspeed You! Black Emperor. If you attended the collective's incredible 2012 Basilica show, you already know the facility's soaring, cathedral-like ceiling makes it a, well, God-given space in which to hear such expansive music. Xylouris White opens. Later that week, the complex will once again be taken over by the Pitchfork-co-curated Basilica SoundScape festival, with Haxan Cloak, Wolf Eyes, Viet Cong, Health, Perfume Genius, Actress, Weyes Blood, and more. Godspeed You! Black Emperor: September 8. 8pm. $20 (special $60 discounted weekend pass to SoundScape available to all GY!BE show attendees). Basilica Soundscape: September 11, 12, and 13. See website for schedule. $70 weekend pass, $40 for September 11 or 12 only, $30 for September 13 only. Hudson. (518) 822-1050; Basilicahudson.com.
