Rolling Stone reports:

Galt MacDermot, who composed the hit Broadway musicals Hair and Two Gentlemen of Verona, died Monday, a day before his 90th birthday. His death was confirmed to Playbill by his granddaughter, though a cause of death was not revealed. With a plot that questioned the Vietnam War, the production of Hair was a timely smash and earned two Tony nominations and won the Grammy for Best Score From an Original Cast Show Album.

MacDermot’s music, both from his stage productions and non-Broadway albums, had an immense impact on hip-hop. Samples of “Space,” from his Woman Is Sweetersoundtrack, have appeared in tracks by Snoop Dogg, Faith Evans and Busta Rhymes (“Woo-Hah!! Got You All in Check”). Additionally, Madlib, MF Doom, Run-DMC and Public Enemy, among many others, have all sampled his music in their recordings.
