Wyzard was a power metal band from San Antonio, Texas. This review on Amazon sums it up pretty well: 

​

This album rocks! if you dig old school Texas metal than you'll love this one and just like old S.A. metal bands like S.A. Slayer, Prezence, & Juggernaut who rock the Alamo city back in the day than you might wanna add Wyzard to the list with songs like crystal city & future knights that kicks a#s why wouldn't you want this in your rock collection?
