LA sisters Karmina cover Maroon 5's "Payphone"

With bandmates James Adams and Jaydon Bean, siblings Kelly and Kamille Rudisill breathed new life into the song by turning it into a sweet acoustic number, backed up by banjo, acoustic guitar, drums and keys.

They do away with Wiz Khalifa's rap interlude, instead mixing in a portion of their own tune, "Slow Down", at the end. Wonderful!
