The duo of Sarah Barthel and Josh Carter have been recent mainstays in the electronica world thanks to their melding of lush vocals, hip-hop beats, samples, and guitars. This year, their profiles have expanded further in part due to their collaboration with Big Boi as the supergroup Big Grams and also thanks to the duo bringing a bigger sound with Three, their third album, which netted them a top 10 Billboard debut. But for the longtime fans that can remember their 2009 and 2010 DC9 shows, it was no surprise when Phantogram once again treated the sold-out 9:30 Club to a powerful performance that incorporated interesting projection tricks and hard-hitting sounds from the rock, hip-hop, and electronic worlds.
