Since first emerging in the late-1990s with songs like “World Premier” and “Rocket Science,” hip-hop’s most committed and dedicated underground rap fans have awaited this moment: This week, longtime favorites MHz Legacy, comprised of rappers Copywrite, Tage Future, Jakki Da Motamouth, and producer RJD2, are releasing their first official full-length album, the self-titled MHz Legacy. (MHz’ fifth and final member, Camu Tao, who passed away in 2008 following a bout with lung cancer, also appears on the album with a number of never-before-heard verses.) The album features the likes of Danny Brown, Blu, Slug (of Atmosphere), ILL BILL, Slaine, and Oh No, along with outside production from Harry Fraud, Marco Polo, and !llmind.

To celebrate the album release, MHz Legacy is releasing “Yellow + Blue,” a track that features fellow underground favorite Blu. The song, produced by Surock, is built around organ stabs and wailing guitar, as Blu takes the first verse, his relaxed flow winding slick wordplay throughout with lines like, “Let them rest in peace/ Ashes to ashes, peace/ Pack an automatic piece/ Cut a classic masterpiece/ Peace to my peeps/ From the streets, off the sheets I release.” Tage Future takes the second verse (“I’m going balls out; your girl’s new lozenges”), and Copywrite closes the track off in high fashion with a brash, wordplay-filled verse, rapping, “Bout to retire from rap/ Create my own genre, master it/ Then retire from that/ Sick of setting fire to tracks.”
