Sweet Hollow is a husband and wife folk rock duo based out of Somerville, NJ. The duo consists of Geoff Keiser (vocals, guitar) and Kristin Gellner (vocals, cajon drum). Kristin grew up in Alexandria right up the street from Ironbound. They play a delicately balanced set of toe-tapping music from across the ages. They put a harmony-focused spin on each song that they cover. They also have written some original music.
