STS9 will open for Jay-Z later this month. The group will support the rap-icon at Denver’s Pepsi Center on Monday, March 22. STS9 will deliver a “a full band LIVE PA Set at 7PM.” The show’s other support acts include Young Jeezy and Trey Songz. The group offered its fans discount upper bowl tickets, though that allotment has sold out. Jay-Z, who sat in with Phish in 2004, will co-headline Bonnaroo this June.
