Da Unit is back. A day after reuniting onstage at Summer Jam, all four members of G-Unit come together on their first song in six years.

50 Cent, Lloyd Banks, Young Buck, and Tony Yayo put aside their differences and get back to business on “Nah I’m Talking ‘Bout,” a remix to Hit-Boy and HS87’s “Grindin’ My Whole Life,” which also features Kidd Kidd.

But that doesn’t mean things can’t go south again. “Everything cool here till I trip,” jokes Fif, whose album Animal Ambition drops tomorrow.

Hear the reunion that’s been years in the making.
