Outkast (typeset as OutKast) is a Grammy Award-winning American hip hop duo based out of East Point, Georgia, a city south of Atlanta, Georgia. The duo was originally known as The OKB (The OutKast Brothers) but later changed its name to OutKast. The group's original musical style was a mixture of Dirty South and G-Funk. Since then, however, funk, soul, pop, electronic music, rock, spoken word poetry, jazz, and blues elements have been added to the group's musical palette. The duo consists of Atlanta native André "André 3000" Benjamin (formerly known as Dré) and Savannah, Georgia-born Antwan "Big Boi" Patton.
The duo is one of the most successful hip-hop groups of all time, having received six Grammy Awards. Over 25 million copies have been sold of Outkast's eight releases: six studio albums, a greatest hits release, and Speakerboxxx/The Love Below, a double album containing a solo album from each member. Speakerboxxx/The Love Below is one of only three hip-hop albums to be certified Diamond in the U.S. for shipping over 10 million units. Along with Outkast's commercial success, it has maintained an experimental approach in their music and is widely praised for its originality and artistic content.
