When the Beastie Boys were inducted into the Rock and Roll Hall of Fame just weeks ago, the New York trio was down a man.
Michael "Mike D" Diamond and Adam "Ad-Rock" Horovitz took the stage with a letter from their missing band mate: Adam "MCA" Yauch, who was too ill to attend. He was suffering from a cancerous salivary gland first diagnosed in 2009.
In the letter, which Horovitz read, Yauch dedicated the honor to his fellow B-Boys, "who have walked the globe with me."
"To anyone who has been touched by our band, who our music has meant something to, this induction is as much ours as it is yours," said Yauch. It was typical generosity from Yauch, the gravelly-voiced rapper who helped make the Beastie Boys one of the seminal groups in hip-hop and whose good-hearted nature led him to humanistic causes and made him beloved in hip-hop.
One of his most famous rhymes was a sweet ode to women, which he called "long overdue": "To all the mothers and sisters and wives and friends/ I want to offer my love and respect to the end." When the news came Friday that earlier that morning, Yauch, 47, had died after a nearly three-year battle with cancer, the words from his letter felt particularly apt. The outpouring of sadness at the loss, and celebration of the music Yauch helped created, was immediate and vast, shared across social media by those close to him, rappers influenced by "Paul's Boutique" and hip-hop listeners raised on Beastie Boys videos.
The rapper Q-Tip, a member of another major New York hip-hop group, A Tribe Called Quest, recalled that the Beastie Boys "showed us the ropes." Sean "Diddy" Combs called Yauch "a true pioneer and a creative force who paved the way for so many of us." The rapper Nas lamented the loss of a "brother": "MCA was so cool," he said.
For Eminem, Yauch was an undeniable touchstone: "I think it's obvious to anyone how big an influence the Beastie Boys were on me and so many others."
Yauch found widespread respect in a hip-hop world with few credible white performers.
In a span of more than a quarter century that covered four No. 1 albums and more than 40 million records sold, the Beastie Boys played both prankster and pioneer - a simultaneously goofy and groundbreaking act that helped bring hip-hop to the mainstream.
The demure, gray-haired Yauch wasn't the most boastful B-Boy; he was the thoughtful one and a steady source of the trio's innovative spirit. A practicing Buddhist, he led the group in performing concerts to benefit Tibet and, as a filmmaker, he helped create their imagery.
"The group's music crossed genres and color lines, and helped bring rap to a wider audience," said Neil Portnow, president of the Recording Academy. "Yauch was an immense talent and creative visionary."
Adam Nathanial Yauch, born in Brooklyn, formed the Beastie Boys with high school friend Diamond. Originally conceived as a hardcore punk group, they played their first show on Yauch's 17th birthday.
In the letter read at the Rock and Roll Hall of Fame induction, Yauch recalled their early days at his parents' home in Brooklyn, "where we used to practice on hot Brooklyn summer days after school, windows open to disturb the neighborhood."
The group became a hip-hop trio soon after Horovitz joined and coalesced after Yauch dropped out of Bard College two years into his studies. Yauch played bass. Later, they would even release an album of instrumentals, which won one of their three Grammys in 2007.
On "Pass the Mic," he rapped: "If you can feel what I'm feeling then it's a musical masterpiece / If you can hear what I'm dealing with then that's cool at least / What's running through my mind comes through in my walk / True feelings are shown from the way that I talk."
For many, the Beastie Boys' lyrics - overflowing torrents of wit, humor and rhyme - were always the main draw. While other forms of hip-hop celebrated individualism, the Beastie Boys were a verbal tag team.
Their popularity perhaps peaked with 1994's "Ill Communication," which spawned several of their most famous music videos, including "Sure Shot" and the Spike Jonze-directed "Sabotage" - a hit highlighted by Yauch's bass solo.
Yauch used the group's growing fame to attract awareness for Tibetan Buddhists. He founded the Milarepa Fund to promote activism for Tibet in defense of what the nonprofit considered China's occupational government.
In 1996, Yauch and Milarepa produced a hugely popular benefit concert for Tibet in San Francisco, which was followed by more international concerts over the next decade.
"He was a goofball and behind a lot of their prankiness, but if you wanted to talk to him about what was going on in the world and social issues and everything, you got a totally different guy," said Rick Krim, executive vice president of music and talent relations at Vh1.
Introducing the group at the Rock Hall, Public Enemy rapper Chuck D said the Beastie Boys "broke the mold."
"The Beastie Boys are indeed three bad brothers who made history," Chuck D said.
