An iconic Americana band, Steve Earle & the Dukes most recently released their 20th studio album J.T., a tribute to Earle’s late son, singer-songwriter Justin Townes Earle. Artist advances and royalties from J.T. are being donated to a trust for Etta St. James Earle, the three-year-old daughter of Justin and Jenn Earle. Expect to hear songs from it as well as tracks from Earle's decades long career when the group performs tonight at 8 at the Kent Stage. Tickets cost $45.
