STS9 (Sound Tribe Sector 9) w/ Ghostland Observatory and Big Gigantic

One of the first improvisational jam bands to use a canvas of electronic- and dance-based sounds instead of rock- and blue-based ones, Sound Tribe Sector 9 is at the forefront of an offshoot of jam music affectionately called jamtronica. They play long, freeform sets, shifting textures like a funkier, more groove-based incarnation of the post-rock band Tortoise, and flaunting a grand-scale light show that, much like the music itself, is largely improvised.
