If you were to ask me, I'd have to say that surf rock is one of the hardest genres to mess up. And shoegaze is probably a close runner-up.
So, given that DIIV has combined both genres on this new track "Bent (Roi's Song)," one can only expect that it comes across sounding pretty solid to the ear.
If you dig it, you can get it as a free download when you pre-order the band's upcoming release Is the Is Are via Captured Tracks.
