Background: Wu-Tang Clan  is an American hip hop group from Staten Island, New York City, originally composed of East Coast rappers RZA, GZA, Ol' Dirty Bastard, Method Man, Raekwon, Ghostface Killah, Inspectah Deck, U-God and Masta Killa. Cappadonna later became an official member of the group. The Wu-Tang Clan has released four gold and platinum studio albums. Its 1993 debut album, Enter the Wu-Tang (36 Chambers), is considered to be one of the greatest albums in hip-hop history.
Context: The group reconvened once again to make The W, though without Ol' Dirty Bastard, who was at the time incarcerated in California for violating the terms of his probation. Though incarcerated, ODB managed to make it onto the track "Conditioner" which featured Snoop Dogg. ODB's vocals were recorded via the telephones used for inmates to talk with visitors, while in prison. The W was mostly well received by critics, particularly for The RZA's production, and also gave the group a hit single with the uptempo "Gravel Pit", part of a trilogy of videos where the group would visit different eras with a time traveling elevator, which also included "Protect Ya Neck (The Jump Off)" and "Careful (Click, Click)", which were then followed by "I Can't Go to Sleep" featuring Isaac Hayes. The album would go on to reach double platinum status.  Shortly before the release of The W, ODB escaped custody while being transported from a rehab center to a Los Angeles court and was considered a fugitive. At a record release party for The W, ODB appeared with his face hidden by an orange parka, and was not recognized until introduced to the crowd. With police officers present outside, ODB performed briefly and then fled, fearing capture. Six days later ODB caused a commotion, signing autographs in a McDonald's at Broad & Girard Street in North Philadelphia. Unaware of who was causing the commotion, the manager called the police. When the law arrived, ODB mistook them for fans until they drew their guns. ODB fled the facility, but was stopped while trying to start his vehicle. After presenting a fake ID, he admitted his real identity, and was arrested.  In 2001, the Wu-Tang Clan released Iron Flag, an album which made extensive use of outside producers and guests. Its crossover vibe and features, including Ron Isley, Flavor Flav, and prominent producers Trackmasters, marked it as a lighter fare; while critically praised, it gained a less than stellar reputation with fans. Group member Ghostface Killah would later denounce the record.  While originally featured on the cover of Iron Flag, Cappadonna was airbrushed out of the artwork and absent from the album entirely. This may be related to tension that arose within the group when it was revealed that Cappadonna's manager was, or had been, a police informant, a revelation that also brought on the manager's subsequent firing. Cappadonna would however, continue collaborating and touring with the group in the upcoming years.  Around this time Method Man began his acting career, along with close collaborator Redman, by starring in the stoner comedy film How High.
