GOING OVERDRIVE WITH Concrete cowboys

CJ Barham and Mikey Alvarado from Concrete Cowboys are all about pushing limits and living life full throttle. In this interview, they spill on everything from dodging cops in Mexico, where CJ ended up in prison after a wild police chase, to pulling off death-defying stunts that almost left them broken. Whether they're crashing bikes in Hollywood or partying with strippers who bail them out of jail, these guys embody the rockstar lifestyle.

Their stories are packed with chaos, adrenaline, and a reckless drive to take things to the edge. From taking over Nashville during their release party to surviving near misses with the law, CJ and Mikey show what it means to ride hard and live harder. The Concrete Cowboys aren’t just a crew—they’re a way of life, and these two are at the heart of it, tearing up the road and the rulebook.
