Joan Baez [ tickets ] has mapped summer tour dates as she continues to back her latest album, "Day After Tomorrow," which hit stores last September.

The iconic folk singer and activist kicks off the trek July 6 in Napa, CA, and the tour currently consists of 23 dates that run through mid-August, concluding with a West Coast slate. Details are listed below for the outing, which is expected to add more cities in the coming weeks.

"Day After Tomorrow," is Baez's 24th studio album and first since 2003's "Dark Chords on a Big Guitar." The new set, which surfaced last fall, was recorded in Nashville with an all-acoustic band featuring Tim O'Brien, Darrell Scott, Viktor Krauss, Kenny Malone and Steve Earle, who penned an original track, "God is God," for the record.

"It's been a long time since I've had an entire album of songs that speak to the essence of who I am in the same way as the songs that have been the enduring backbone of my repertoire for the past 50 years," said Baez in a press statement.

The album became her first full-length release to hit the charts in the US in 29 years, reaching No. 128 on The Billboard 200 in its debut week.

In 2005, Baez released "Bowery Songs," a collection of live recordings from her Nov. 2004 performance at New York City's Bowery Ballroom. That set includes four songs the singer had never recorded before: "Seven Curses" (by Bob Dylan), "Jerusalem" (by Earle), "Finlandia" and "Dink's Song."
