Look out for singer/songwriter Sierra Heuermann and her band The Radicals. She got to sing with indie icons Muse after submitting a cover song via a contest. Sierra notes, ” I sang “Starlight” with the band. Right before I was scheduled to go on, I was told that I would be singing alone, without Matt, and that the key was going to be lower than the recording, meaning I wouldn’t be able to use anything I had practiced.” She just dropped the electro pop track You Look Like My Next Ex which is pretty good and is garnering some blog love. Give it a listen!
