They promise it's worth the trip.

The tagline practically writes itself: "It's Worth the Trip."

That's the tease for a just-announced summer tour featuring three of the most-acclaimed singer-songwriters in modern music. The LSD tour will bring together Lucinda Williams, Steve Earle and Dwight Yoakam for the first time on a North American outing.

The trek will kick off on June 12 at the Blue Hills Bank Pavilion in Boston, Massachusetts and then hit amphitheaters and theaters across the country, before winding down on Aug. 18 with a show at the Farm Bureau Insurance Lawn in Indianapolis, Indiana. The tour will also include an opening set from King Leg.

Williams is hitting the road in the wake of her recent re-recording of her iconic 1992 album Sweet Old World, while Earle is touring in support of the 30th anniversary of his classic Copperhead Road. Yoakam recently announced the upcoming late April launch of Yoakam's "Dwight Yoakam and The Bakersfield Beat" radio station on SiriusXM, which will feature music from throughout the country legend's career, as well as a celebration of California country and country rock.
