Don Toliver started building hype for his new album Nitrous after dropping a message on Instagram Story on Sunday, Aug. 2. This announcement landed two days before his Octane World Tour's second leg kicks off. That album moved 162,000 units during its opening week and racked up 139 million on-demand streams. Producer and rapper J Young MDK claimed in July that he'd listened to the finished album already. The Nitrous leg of the Octane World Tour starts on Tuesday, Aug. 4 in Sacramento.
