McCafferty is a dance punk project, started by Nicholas Hartkop as a solo project. Formed in 2012, the band has had a tumultuous history, repeatedly breaking up and rejoining. The most recent break up in 2020 shedded the rest of the original full-band line-up that joined Hartkop, as allegations of abuse from Harktop surfaced from now former band members, who formed their new band Sister Sandy afterwards. Hartkop, and thus McCafferty, once again vowed to never make music again.
