The first Big Grams outing, “Fell In The Sun” arrived last with as some form of large, glossy and carefree pop music. A week later, Big Grams returns with another single in “Lights On” that is equal parts rhythmic and cool and led heavily by Phantogram’s Sarah Barthel with Big Boi bringing in the anchor leg. Stream “Lights On” from Big Grams below. The group’s debut EP together lands next Friday and you can pre-order it on iTunes.
