British music writer Richard Havers and producer Russ Titelman will discuss Satchmo: Louis Armstrong-Ambassador of Jazz, a handsomely packaged new 10-disc box set which includes a fair amount of previously unreleased material. Here’s Armstrong in 1959 in Germany performing “Basin Street Blues.”

By the way, OffBeat is giving away a copy of the Satchmo box set. To be eligible to win, subscribe or buy someone a gift subscription to OffBeat during the month of August. The winner will be announced in the September 8 edition of “The Weekly Beat.”
