R5 is an American Pop Rock band based in California. Formed in 2009, the band consists of four siblings and their friend from Littleton, Colorado: Ross Lynch, Riker Lynch, Rocky Lynch, Rydel Lynch, and family friend Ellington Ratliff.
In March 2010 they self-released an EP entitled "Ready Set Rock" and are currently working on their debut studio album with Hollywood Records.
Since the beginning of 2012 R5's popularity has increased significantly due to Ross's starring role in the hit music-based sitcom Austin & Ally (which led to the signing of R5's recording contract with Hollywood Records) and Riker's recurring role in Fox's musical drama Glee.
The band went on a mini Tour Club sponsored by Radio Disney, entitled R5 West Coast Tour. On June 1, 2012, it was announced that the band will be playing at the Big Ticket Summer Concert singing Say You'll Stay in Canada put on by Family Channel alongside Bridgit Mendler (Ready Or Not), Mimoza Duot (LOVE), Allstar Weekend (Not Your Birthday Day, Blame It On September, Come Down with Love and Dance Forever), Veronica (Incompatible) and Tyler Medeiros (Say I Love You and Girlfriend), with hosts Ed Witzke, Demetrius Joyette, Ana Golja and more. Riker Lynch announced on his twitter October 15, 2012 that R5 will do a 3MTour and an East Coast Tour.
