SIRIUS XM will debut 31 Minutes to Takeoff August 1 at 10:00 pm ET on SIRIUS XM Hits 1 (SIRIUS channel 1) and XM’s 20 on 20 (XM channel 20). 31 Minutes to Takeoff (J Records) officially goes on sale August 10.

“I can safely say the record sounds like absolutely no other music on the market,” said Posner. “I couldn’t be more excited for SIRIUS XM to unveil the album in such a major fashion. Time will reveal the significance of the events of August 1st.”

SIRIUS XM announced this week that Posner will launch his own SIRIUS XM show, The Mike Posner Show, on September 10 on SIRIUS XM’s Faction (SIRIUS channel 28/XM channel 52), SIRIUS XM’s 100% commercial-free music and action sports lifestyle channel.

Coach K on Mike Posner

On SIRIUS XM, Posner joins another accomplished Duke luminary, men’s basketball coach Mike Krzyzewski, who hosts his own talk show, Basketball and Beyond with Coach K, on SIRIUS XM’s Mad Dog Radio channel. While at Duke, Posner produced a song that played in famed Cameron Indoor Stadium to introduce the team before Blue Devils basketball games.

“Duke students are known for balancing their studies with extracurricular activities, but what Mike has done is really extraordinary,” said Coach K. “It’s terrific to see someone accomplish so much at such a young age and I look forward to having another Blue Devil on our team at SIRIUS XM.”
