First ladies of white rap Northern State and funky Los Angeles collective The Wylde Bunch will accompany on the first couple weeks of the tour, before Definitive Jux representative C-Rayz Walz takes over support duties June 13. California hip-hop veterans The Pharcyde will join a few days later and appear on most West Coast dates.

The trek is scheduled to wrap July 5 in New Orleans.

Last fall, the X-Ecutioners toured the U.S. with Z-Trip, Q-Bert and others on the aptly named Scratch Tour. The group, originally formed by Roc Raida in 1989 as the X-Men, built its rep on live performance. By the time the record labels came calling in the mid-’90s, the four-piece outfit had years of experience at DJ battles, exhibitions and plain old shows.

Revolutions is the fourth full-length album from the pioneering group, which now comprises Roc Raida, Rob Swift and Total Eclipse.

Northern State’s sophomore effort, All City, is set for release in July, and The Wylde Bunch’s debut album, Wylde Times At Washington High, comes out June 29. The Pharcyde will join in the summer fun with its first album in four years, Humboldt Beginnings.

C-Rayz Walz is currently supporting last year’s Ravipops.
