Tori Kelly (and Angie Girl)
YouTube Channel: ToriKelly
At 18, Kelly is already something of a music business vet. She was signed to Interscope in 2007 after a winning performance on the short-lived series America's Most Talented Kid. (She was dropped before she could release an album.) Then, in 2010, she turned up as a contestant on American Idol season nine, but didn’t get past Hollywood week. Perhaps she's ready for a third act: On her YouTube channel, Kelly is deservedly racking up views for both her originals and covers. She does an excellent undersell of Ocean's "Thinkin Bout You," keeping the production both visually and musically sparse – just Kelly on vocals and guitar and her friend Angie providing subtle, solid beatbox accompaniment. Her falsetto is sweet and flawless, as is her earthier register, but it's nice to hear her let it rip near the end, showing off the vocal power she's held at bay elsewhere.
