Indie folk duo Okdal's greatest strength lies in Yoon-joo Kim and Sae-jin Park's audible chemistry. It's been there since the pair met in 2007 as university music students, and it's clear from the harmonious pairing of their voices on the 2011 single “Cheer Up.” The music they make together is sweet, soft, and earnest, with gentle acoustic instrumentation that cushions the heavily emotional lyrics of songs like “Could I Leave.”
