Primal Impulse formed in October of 2012 and arrived on the Houston music scene in January of 2013. Formed by Lance Klepper (formerly of Failed To Reason), Adam Bomb (formerly of Lone Star Porn Star), Cody Slade (formerly of Black River Virus), and James "J.D." Garza (formerly of The Apostles). Having already been compared to the likes of Godsmack, Korn, Pantera, And Disturbed all melted together in a pot of metal, Primal Impulse is forging ahead with a chemistry and cutting-edge sound like no other. They are already booking shows in the Houston and surrounding areas, and open to networking with other regional bands to trade shows with.
In November 2013, Adam Bomb Decided to leave the band for personal and musical differences. Primal Impulse is currently auditioning guitarists in the Houston area.
