It’s no secret that the depressed economy has finally caught up with that last bastion of revenue for musical artists: touring.

Even marquee artists are finding themselves playing to far less than full houses, with promoters offering a host of premiums and discounts in order to get as many butts in seats as possible.

But for Minneapolis independent hip-hop stalwarts Atmosphere, it might as well still be 1999. Spending the better part of the last decade working the road harder and more intensely than most touring bands has resulted in a massive, dedicated and exponentially growing audience of fans that continue to fill larger and larger venues.

The act recently filled the legendary Red Rock amphitheater outside of Denver, reportedly selling upward of a staggering 8,300 tickets. And on a Wednesday night in L.A., Atmosphere sold out the 4,000-capacity Hollywood Palladium, an especially impressive feat for an independent act of blue-collar dudes from the Midwest.
