Rap crews are on their way back in vogue.

Seriously. It's something that's discussed in the March 2001 issue of XXL (on sale now). Think about it. With Eminem, Slaughterhouse and Yelawolf joining forces, you have to figure more rappers will be building their respective armies. Plus, we can't forget about Wayne and his Young Money crew, Kanye's G.O.O.D. Music squad and Jay-Z's ever-expanding Roc Nation roster.

In celebration of our new issue release, we've compiled 20 of the best hip-hop crew compilations in no particular order. Different from established groups, these crews—a loose collection of spitters often on the same label who came together on occasion to offer some musical output. Rather than an album with centralized themes and clear cohesion, as many often have, these are crew compilations—a gathering of cuts that typically don't rely on one another. Some have came in the form of movie soundtracks that showcase a crew's roster, some are exhibitions of what a certain label had to offer, and some were simply a reason for a bunch of musically-linked friends to come together.

Murder Was The Case (1994): This compilation had a gang of singles including “Woman to Woman,” “Murder Was The Case,” “Natural Born Killaz,” “U Better Recognize” and “What Would U Do.” It was the soundtrack to a short film starring Snoop directed by Dre and Fab Five Freddy, which reached the No. 1 spot on Billboard 200.
