Among the hip-hop world’s most important artists stands A Tribe Called Quest, the seminal and ground-breaking group that inspired legions of fans and musicians. Group co-founder Phife Dawg, also known as Malik Taylor, died Wednesday at the age of 45.

Fellow artists soon took to social media to post remembrances of Phife Dawg, who had been battling diabetes for years. He died from complications from the disease, his family said in a statement.

Kendrick Lamar, who began touring Australia this week, led an audience in a “Phife Dawg” chant as a tribute to the fallen rapper.

“We lost one of the pioneers in hip-hop today by the name of Phife Dawg,” he told the crowd, in video captured and posted on Facebook. “So right about now, we’re going to give it up for him, for allowing me to do what I’m doing on this stage right here right now today.”

Questlove described the first time he and fellow Roots crewmate Black Thought heard Phife Dawg’s lyrical prowess in a dorm room in 1991. They had just purchased “The Low End Theory.”

“The sign of a true classic is when a life memory is burnt in your head because of the first time you hear a song,” Questlove wrote on Instagram. They listened to “Buggin’ Out.”

“Malik ‘Phife’ Taylor’s verse was such a gauntlet/flag planting moment in hip hop. Every hip hop head was just…stunned,” Questlove wrote. “By the time we got to ‘Scenario’ I swear to god THAT was the moment I knew I wanted to make THIS type of music when I grew up–(yeah yeah dad I know: ‘go to Juilliard or Curtis to make a nice living at “real music”) but he didn’t know that Phife & his crew already wrote my destiny. I ain’t look back since. THANK YOU PHIFE!”

Talib Kweli tweeted, “Today is a dark day in hip-hop.”

“It’s like I just lost a parent in a sense,” 9th Wonder wrote on Instagram. “You gotta understand the identity that Tribe gave to a 15 year old black kid like me who felt like other artists/groups in 1990, although great, just didn’t fit my persona.”

He continued: “Musically, it not only affected me, but so many others. Tribe has a family tree of [its own]…and one of the very roots we have sprouted from, is gone.”

Other artists, musicians and even elected officials shared their condolences and tributes on social media.
