Known for a blistering live show, the quintet attracted attention from major labels after only a handful of performances. An offer from Island/Def Jam materialized after the Bronx's 12th gig, but the band decided to issue several recordings on its own label, White Drugs, before partnering with a major. Former Guns N' Roses guitarist Gilby Clarke helped the Bronx compose an intense rock sound for their first demo, and the band's debut, The Bronx, appeared in August 2003 via the Ferret Records label. Three years later, a second self-titled album marked the band's first effort for Island Records, and the band supported its release by joining Priestess, the Riverboat Gamblers, and Wires on Fire on the WHODOYOUVOODOO Tour.

The quintet then parted ways with Island and issued a third eponymous release, unofficially known as The Bronx III, with help from Original Signal Recordings. Also in 2006, after being asked to play an acoustic set, the Bronx gave their sound a new spin, shifting from hardcore to Latin sounds. This led to the formation of alter ego band Mariachi el Bronx, who made their recorded debut in 2009. In 2013, a fourth volume of proper Bronx material arrived. IV leaned more toward a polished hard rock approach than the group's earlier, punkier sound. ~ Andrew Leahey & MacKenzie Wilson
