Dire Straits frontman Mark Knopfler will sell off a collection of guitars he considers “old friends” at a Christie’s auction in London next year.

FILE - This July 15, 2018 file photo shows Jason Isbell, of Jason Isbell & The 400 Unit, performing at Forecastle Music Festival in Louisville, Ky. Isbell is king of the Americana genre, but he's ambitious for more. The 2013 breakthrough album Southeastern established Isbell as an important new voice and two vibrant follow-ups proved that wasn't a fluke. With Lucinda Williams and t he late John Prine, Isbell formed a holy trinity for fans of Americana music. But Isbell wanted production touches that could help the disc Reunions appeal to people who might not listen to Americana music. Isbell, a progressive with no interest in seeing Trump re-elected, will likely face those issues himself in an election year.
