Flowchart (aka Sean O'Neal) is a one-man electronica outing from Philadelphia. Between 1994 and 2003, Flowchart was a band, consisting of O'Neal, Craig Bottel and Brodie Budd (until 1997), and Erin Anderson (from 1997 onwards). In 2003, Anderson left the band, and the Flowchart moniker was shelved; O'Neal began recording as Someone Else, while Anderson founded a combination hair salon, music club, and art gallery in Philadelphia called "Fringe". The moniker was revived by Sean O'Neal in 2015 for the release of Post-2000 Getup
