The Grateful Dead Channel will make its debut on September 7 at 12 pm ET on SIRIUS channel 32 with an extremely rare concert broadcast of the band’s 1974 performance at the Hollywood Bowl in Los Angeles, California.

"Since we announced the launch of the Grateful Dead Channel, it has become one of the most anticipated music channel launches in our history.” said Scott Greenstein, President, Entertainment and Sports, SIRIUS. “The loyalty and passion of Grateful Dead fans are the truest testament to the band’s legacy.

“This is gonna be one fun channel,” said the Dead’s Bob Weir. “We, the guys in the band, get to be involved as much as we can and we'll make sure it's fun. We want the fans to be involved as well.”

The Grateful Dead formed in mid 1960’s San Francisco’s psychedelia and quickly became a staple in the local music scene. The historic summer of 1967, known as ‘The Summer of Love,’ is when the band first found world wide recognition as thousands of young people from around-the-world made their way to San Francisco’s Haight and Ashbury district to find a new social experience. The Dead, well-known for constantly touring, kept the experience alive for another three decades with a devoted community of fans, many of whom traveled the country with them.

The Grateful Dead Channel joins an exclusive line up of 24-hour, commercial-free music channels dedicated entirely to some of the world's greatest recording artists including Elvis Radio, the world's only official, all-Elvis Presley radio channel broadcasting live from Graceland; and Siriusly Sinatra, devoted to the music and legacy of Frank Sinatra.
