In our brand new January 2011 issue, John Swenson interviews trombonist Delfeayo Marsalis for our Backtalk interview about his upcoming release, Sweet Thunder. The album is a reworking of a Duke Ellington suite of the same name, for which Ellington wrote 12 compositions based on plays and sonnets of Shakespeare.

Here’s Marsalis performing his new album’s closing track, “Circle of Fourths”, about three years ago.
