Fergie and the Black Eyed Peas haven't played together in five years, but they will be playing separate concerts in Philadelphia during the Democratic National Convention on Wednesday.
The Black Eyed Peas are listed as headliners for a Rock The Vote concert at the Fillmore Philadelphia, while Fergie is headlining a concert for the Creative Coalition the same night.
The Grammy-winning rap group, which also includes members Will.i.am, apl.de.ap and Taboo, had multiplatinum hits with songs like "Boom Boom Pow," and "I Gotta Feeling."
Fergie joined the band as a singer in 2002. The band announced it was going on a hiatus in 2011.
