Main stage highlights from the opening night of the four-day 2012 Sasquatch music festival:

Pittsburgh, Penn., DJ Girl Talk played fusion hip-hop/pop/rock at sunset; afterwards fireworks launched from the scaffolding.

Girl Talk's fireworks

Seattle rapper Macklemore performed after Girl Talk, unannounced — unless you caught his cryptic messages earlier on Twitter. His "Irish Celebration" anthem was enthusiastically received.

Pretty Lights, a pop rave act from Colorado, prompted everyone in the crowd to throw glow sticks into the air from what seemed like an unlimited supply.
