The founder member of the Dave Matthews Band died in August
Fans of the late saxophonist LeRoi Moore have reacted angrily after the musician was not included during the annual Grammys video obituary tribute.
A Facebook group and online petition are demanding an apology from The Recording Academy.
Grammy said time prevented it from including all "talented and wonderful people" that had died last year.
The star was listed in the program book with all the other musicians who have passed away in the last year.
Moore was a founding member of the Dave Matthews Band.
Dave Matthews himself commented via his Twitter account.
"We all know what a great man Mr Moore was, we remember him.
"The Grammies [sic] are not my cup of tea."
Grammy president Neil Portnow said in a statement: "Nearly 250 members of our music community have passed in the last year, and all of them have been listed in the program book for the 51st Annual Grammy Awards, including LeRoi Moore.
"For the 'Encore' segment of our annual Grammy Awards telecast, unfortunately we are unable to include all of the talented and wonderful people within the allotted timeframe.
"The Academy recognizes Moore's contributions to music and music education and we are deeply saddened by his premature passing."
Moore died, aged 46, after a vehicle accident on his Virginia farm in June.
