A phantogram is a type of optical illusion, and also a cool band name for the duo of Josh Carter (guitar and vocals) and Sarah Barthel (vocals and keyboards). The two friends have known each other since junior high school, and formed their musical collaboration in 2007 in upstate New York. At first, they called themselves Charlie Everywhere, playing gigs and recording some small label EPs. In 2009, they changed their name to Phantogram, and released their debut album in the fall of that year. Three is, of course, their third full-length. Phantogram's music can be described as electronica, trip hop or dream pop. Whatever you call it, Three is an appealing, well-crafted pop record.
