There are songs that you listen to when you're feeling down, when you're feeling focused, and others that you listen to when you feel like jumping around your bedroom and reliving your 8-year-old Lisa Frank days. PHASES' music works for all of those occasions and just about any other scenario you could think up. With their own brand of electro pop, the group—comprised of Z Berg, Jason Boesel of Rilo Kiley, Alex Greenwald of Phantom Planet, and Michael Runion—has been at the forefront of the synth-infused sonic movement. So when we asked them to perform an acoustic version of their song "Cooler," we were interested to see how it would come together. What resulted is our new favorite chill song.
