Our favorite singing kid sisters blow us away in new video

Last time, kid sisters Lennon and Maisy blew us away with an a cappella cover of Robyn/Erato’s “Call Your Girlfriend.” This time, they perform a haunting version of Imogen Heap’s “Headlock”—and suffice it to say, they’ve officially won our hearts. With 12-year-old Lennon effortlessly gracing an acoustic guitar and 8-year-old Maisy singing backup, the duo croons heart-wrenching lyrics and harmonies with a sheer mastery that would seem beyond their age. It’s a good thing we’ll be seeing much more of them soon, and not just on YouTube: the sisters will be joining the cast of ABC’s “Nashville” this fall alongside Hayden Panettiere.
