After slowing down its tour schedule this summer, Sound Tribe Sector 9 returned at full force this weekend with a pair of Colorado performances. On Friday, STS9 kicked-off its fall tour in front of an overflowing crowd, playing an extremely intimate show at Boulder, CO’s Fox Theatre. On Saturday the group performed at Morrison, CO’s Red Rocks Amphitheatre with Jurassic 5. To mark the occasion, the group played ‘HB Walks To School’ for the first time in 7 years, offered the debut of’ You Don’t Say’ and unveiled the recently revamped version of ’986 Foot Tall Trees.’ STS9 will perform at Lawrence, KS’s The Granada Theatre tonight.
