Best known for Songify This, Auto-Tune the News, and their collaborations with artists on YouTube — including "Bed Intruder Song," "All The Way," and "Chicken Attack" — the Gregory Brothers are primarily a YouTube music and comedy troupe that run the YouTube channel Schmoyoho. In 2007 they formed an indie band with brothers Evan Gregory (keyboards, vocals), Andrew Rose Gregory (guitar, vocals), Michael Gregory (drums, vocals), and also with Evan's wife Sarah Gregory (bass, vocals). After their breakout series Auto-Tune the News, the group honed the form of "songification," using pitch correction software to create songs and duets with "unintentional singers" and many collaborators. They draw influence from several genres, often targeting a style that matches the unintentional singer's voice.
