The stacked lineup for One Musicfest just got a little bigger – as in Big Boi bigger.

The rapper, along with songstress Monica, has been added to the Sept. 9 schedule of performers, which means it will be a massive Atlanta-based day with 2 Chainz, T.I. and crunk veterans East Side Boyz and Trillville already set to play.

The event will be held Sept. 8-9 at Central Park.

One Musicfest tickets are $125 for two-day general admission (price increases to $140 on Sept. 7); $75 for single-day general admission; $250 for two-day VIP; and $750 for two-day platinum. Visit www.onemusicfest.com for more information.
