Mat Kearny on a Southwest Airlines Flight – Strangest Concert Locales

What's higher than the CN Tower? How about playing on an airplane cruising at an altitude of 35,000 feet? That's exactly what Mat Kearny did when he performed on a Southwest Airlines flight, possibly setting an entirely new record for World's Highest Concert while singing into the phone that flight attendants use to make announcements. The Nashville-based Kearny, who is best known for his 2006 album 'Nothing Left to Lose,' later called the gig "cool."
