Multiple artists share the name Mainland. 1. Mainland is made up of four New York City transplants – by way of California and Upstate New York – who met each other at rooftop parties in the summer of 2010.

Rolling Stone, French Elle, Consequence of Sound, and Interview Magazine have all since touted the group.
