As part of their forthcoming North American tour, Wavves and Best Coast put together the split 7″ featuring two previously unreleased tracks. You can hear Wavves’ contribution, a King of the Beach bonus track called “Stained Glass (Won’t You Let Me Into Yr Heart)”, here. Now, thanks to It’s the Supersound, check out the brand new Best Coast song “When You Wake Up” below.

In addition to the 7″ single, which is available only at the bands’ upcoming dates, the two songs are also packaged in a new iTunes digital sampler.
