Around this time, Marciano formed the U.N., made up of Dino Brave, Laku, and Mike Raw -- all high-school classmates at Long Island's Uniondale. Together, they appeared on Pete Rock's PeteStrumentals and released their buzzworthy mixtape Strength & Honor and the 2004 LP UN or U Out? Soon, though, the crew disintegrated; they found it hard to get industry traction. Marciano forged on by dropping verses on GZA's Pro Tools and Marco Polo's Port Authority. In 2010, he released Marcberg, his official solo debut album. He handled all production, and wrote and rhymed all but one verse. It was hailed by New York underground hip-hop royalty. The following year, he teamed up with the Alchemist and Oh No for the Greneberg EP. LUV NY, a supergroup set featuring Marciano beside the likes of Kool Keith and A.G., was released in July 2012. A few months later, Marciano issued his second proper album, Reloaded, which was mostly self-produced but also included the Alchemist as well as Q-Tip. Critical praise nearly equaled the level of Marcberg.
Marci Beaucoup appeared at the end of 2013, with many features (including frequent contributors KA and Knowledge Pirate, plus Freeway, Guilty Simpson, Action Bronson, Evidence, and Cormega). Marciano spent several years lying low, but was featured on a track from De La Soul's And the Anonymous Nobody. He finally emerged in 2017 with his fourth album, Rosebudd's Revenge, which included few guests but more outside production (from beatmakers including Knxwledge, the Arch Druids, and Mushroom Jesus). ~ Vincent Thomas, Rovi
