Chrysalis Music Group A&R exec Brett Cantor was found slain in his Hollywood home July 30, according to Los Angeles police.

Cantor, who was also a partner in Hollywood’s Dragonfly nightclub and was well-known as a local promoter of underground parties known as “raves,” died of multiple stab wounds, according to police.

No motive has been established for the slaying, but the investigation has been moved to downtown police headquarters from the Hollywood precincts, according to the police. Cantor was last seen leaving Club 434 in Hollywood in the early hours of Friday morning.

Cantor, 25, was a well-known figure on the Los Angeles nightclub scene. He was a 10% owner of Dragonfly, where he hosted the popular Wednesday night series Superfly (a takeoff on the ’70s featuring disco music) and the Friday night series Riot, a hip-hop club.

A consultant to several music firms, Cantor was said to have been instrumental in the discovery of Rage Against the Machine, an act that was one of the hits of this year’s Lollapalooza Festival tour.

Cantor was born in New York and moved to Los Angeles in 1971.

He worked for a brief time at Agency for the Performing Arts and later founded his own company, Underground Entertainment, which promoted some of the largest live concert and dance events in the city over the last five years, including Petting Zoo, Sanitarium, After Hours and L.A. Palooza.

Survivors include his parents, Paul and Rhonda Cantor; his grandmother and two brothers. Funeral services will be held Aug. 4 at 11:00 a.m. at the Tanach Chapel, Mount Sinai Memorial Park in Burbank.

In lieu of flowers, the family requests donations in Cantor’s name to City of Hope, c/o Tom Sturges, president of Chrysalis Music Group in Los Angeles.
