It’s been 21 years since Long Beach, California MC and producer Warren G released his debut album, Regulate…G Funk Era. The triple-Platinum selling LP is home to his duet “Regulate,” a West Coast classic featuring the late Nate Dogg that remains his most successful track to date. Also housing the top-ten hits “This DJ” and “Do You See,” the album remains a staple for any fan of G Funk, the predominant sound coming out of Los Angeles-area Hip-Hop at the time.

Five solo albums (and one 213 LP) later, and Warren G remains a true proponent of “gangster” funk, opting to name his latest EP after his debut. More than just a follow-up to his own sound, the EP is giving Heads an opportunity to celebrate the life and legacy of Nate Dogg, whose unreleased vocals are featured prominently throughout the project. The singer and rapper passed away in 2011, leaving a gaping wound in Hip-Hop that, according to most, will never fully heal. Thus far, Warren G has released two singles, both incorporating previously unheard Nate Dogg work. The album’s lead single, “My House,” was released last month and earlier this week, “Keep On Hustlin‘” dropped, which also features Young Jeezy and Bun B.

The 5-track Regulate…G Funk Era Pt. II will be released tomorrow and is available for pre-order on iTunes. In the meantime, enjoy the full E.P. stream right here.
