Melvin Seals & JGB have revealed a couple of news bits regarding their upcoming tour dates, including a lineup change and the addition of special guest vocalist/trumpeter Jennifer Hartswick for a batch of fall gigs.

First of all, Sunshine Becker is parting ways with the group, and her position alongside fellow singer Lady Chi will be filled by new JGB member Mary-eL who, the band’s statement notes, has played with Seals and JGB touring guest guitarist John Kadlecik in the past, including at Virginia’s LOCKN’ Festival in 2015. Mary-eL’s first JGB gig will be Oct. 5 in Mitchell, KY.

“The addition of John Kadlecik has brought forth a positive energy we haven’t felt in some time,” JGB’s statement begins. “It’s been fun, exciting and we have a lot to look forward to! Change is inevitable and it’s important that the music always pushes forward and never takes a step back.”

The group also announced the fall tour inclusion of Hartswick, who will be joining JGB on the second half of the dates.

Next up for Seals, JGB and Kadlecik is a duo of shows this weekend in Minnesota and South Dakota, followed by California’s Santa Cruz Mountain Sol Festival next weekend and three nights at Terrapin Crossroads in San Rafael, CA, Sept. 26–28. Check out the band’s full schedule here.
