The Madden Brothers

Established in 2011 as a side project for Good Charlotte's Joel and Benji Madden, the Madden Brothers allowed the siblings room to flex their musical muscles in ways that their pop-punk meal ticket band hadn't. The group issued a free mixtape in 2011 titled Before, Volume 1 that featured a slew of guest appearances from the likes of the Cool Kids, Wiz Khalifa, Machine Gun Kelly, and Casey Veggies, but it wasn't until 2012, when the duo began working with producer Pharrell Williams, that the schematics for a proper studio album began to emerge. Though the plans for the project with Williams eventually fell through, the brothers continued to work on material, and in 2014 issued the summery pop single "We Are Done." The Madden Brothers' Eric Valentine- and Joe Chiccarelli-produced full-length debut, Greetings from California, was released later that year.
