Little by little, there are more shows coming together as part of the proposed Marilyn Manson and Alice Cooper trek. After only a handful of dates initially surfaced, the two rockers have fleshed out the itinerary to span the entire month of June.

At present, the 'Masters of Madness: Shock Therapy' tour currently begins at Red Rocks Amphitheatre in Morrison, Colo. The trek winds through the Southwestern U.S., before detouring in the Midwest to Cleveland and through the upper Midwest. The trek is currently scheduled to wrap in Rockford, Ill. on June 28.

In addition, Manson has also announced a pair of warm-up shows just prior to the trek. He'll be performing in San Diego, Calif., and Tempe, Ariz., on May 29 and 30, respectively, in advance of the run with Cooper. Some of the tickets for the dates announced have gone on sale, while other ticketing details still have yet to be revealed. To stay up to date, check Manson's website here.
