Metal Mama has 1 Vain concert.

1) Sleaze Rock Band: Bursting onto the scene in the late 80s, Vain made waves and appeared on the covers of some of rock and metal's most respected magazines before they even signed a record deal. While toting similar edgy apparel to current glam metal contemporaries, Vain's MO in the Bay Area scene was having actual substance to their music rather than churning out the same three recycled chords like so many rip off bands were making money doing.
