Ranging from quintet to septet , the band is known for its unique and eclectic style , which fused elements of rock , psychedelia , experimental music , modal jazz , country , folk , bluegrass , blues , reggae , and space rock , for live performances of lengthy instrumental jams , and for their devoted fan base , known as `` Deadheads '' . `` Their music , '' writes Lenny Kaye , `` touches on ground that most other groups do n't even know exists . '' These various influences were distilled into a diverse and psychedelic whole that made the Grateful Dead `` the pioneering Godfathers of the jam band world '' . The band was ranked 57th by Rolling Stone magazine in its The Greatest Artists of All Time issue . The band was inducted into the Rock and Roll Hall of Fame in 1994 and a recording of their May 8 , 1977 performance at Cornell University 's Barton Hall was added to the National Recording Registry of the Library of Congress in 2012 .

After the death of Jerry Garcia in 1995 , former members of the band , along with other musicians , toured as the Other Ones in 1998 , 2000 , and 2002 , and the Dead in 2003 , 2004 , and 2009 . In 2015 , the four surviving core members marked the band 's 50th anniversary in a series of concerts that were billed as their last performances together .
