Speakerboxx/Love Below was two solo albums, Dre & Big only collaborated on 2-3 tracks. Idlewild was a period piece from the 30s.
So it’s been 12 years since Stankonia dropped.
And when you think about it, Southernplayalisticadillacmuzik came out in 1994, so they put out albums for six years until 2000.
Outkast has been inactive for twice as long as they were active and releasing music together.
