In addition to Brandy, Sean Garrett has been in the studio working on new music for megastars including Dr. Dre, Kelly Rowland, and Justin Bieber. During his interview with Rap-Up TV, he shared his respect for Dre and his contributions to Detox.
“He got a lot of stuff. You just
be hoping and praying that you make the album,” said Garrett. “We did a
lot of great work, so I’m pretty sure that hopefully I’ll at least have
one on there.”
