As promised last week, Birdman and Rick Ross come through with their collaborative mixtape.

Earlier today, the YMCMB and Maybach Music Group bosses released their collaborative project The H: The Lost Album, Vol. 1. The project—which is hosted by YMCMB's DJ Khaled—was a previously recorded album that the duo originally cut in 2008.

"We'd go to the studio, bang out five, six, seven records, then go shoot us some shit, jump in the Rolls Royce and swerve," Ross said of the recording process in last week's PSA. "We did so much music and we've just been sitting on it, and when we get together we'll listen to it and smoke somethin'. Stunna just hit me like, 'Man, let's go feed the streets with that.'"

Check out the full mixtape below.
