The 2014 Metal All-Stars tour just added another all-star -- Motley Crue frontman Vince Neil. Though the singer is not around for all of the Metal All-Stars shows booked for next March and April, he will perform during the April stops in Europe and Russia.

Former Megadeth drummer Nick Menza is among the organizers for the trek, and a pair of promotional trailers have surfaced for the March and April shows. One of the trailers can be seen above, while the other is featured below.

Menza says, "I'm totally pumped and honored to get the opportunity of sharing the stage with some of the largest and legendary voices in heavy metal. It's definitely going to be an interesting and unique tour, something European and South American fans don't want to miss and I'm hoping it hits the States."

In addition to Neil and Menza, other performers taking part in the run include Philip Anselmo, Anthrax's Joey Belladonna, Black Label Society's Zakk Wylde, U.D.O.'s Udo Dirkschneider, Venom's Cronos, Soulfly's Max Cavalera, Shadows Fall's Brian Fair, Matt Bachand and Jon Donais, former Manowar member Ross the Boss, ex-Shinedown guitarist Jasin Todd, Rob "Blasko" Nicholson and more.

The Metal All-Stars tour will also offer unique items and experiences that will raise funds for the Ride for Dime charitable organization. The trek officially gets underway March 23 in Sofia, Bulgaria, with stops booked through April 9 in Moscow, Russia. For more info on the trek, check the Metal All-Stars website.
