BigXthaPlug’s attorney pledged to fight misdemeanor gun and drug charges after the rapper’s album release party was abruptly canceled following his arrest in Dallas.

An officer asked the driver, identified as Landum, if he had a firearm. BigXthaPlug told officers he did and detailed where to find it in the truck. Police said a criminal database flagged Landum as connected to a gang in Arlington, which meant he was not legally allowed to possess a gun.

The 27-year-old artist born Xavier Landum released a country-crossover album, “I Hope You’re Happy,” on Friday.
