Three major concerts didn’t survive when Indianapolis Motor Speedway moved this year’s Indianapolis 500 from May 24 to Aug. 23.

The Carb Day, Legends Day and Indy 500 Snake Pit concerts — an informal festival of rock, country and electronic styles leading up to the IndyCar race — are canceled.

Track officials cited the coronavirus pandemic in postponing the Indy 500.

Cancelling REO Speedwagon and Styx on Carb Day, Luke Bryan on Legends Day and Martin Garrix and other EDM acts for the Snake Pit show will "provide the maximum flexibility possible to complete the Indianapolis 500 by Sunday, Aug. 23, and provide room for any contingency plans necessary,” officials said in a statement.

Nearly 30,000 attendees were expected for the Snake Pit, a Race Day party that debuted in 2010.

Carb Day, which trails only Race Day in attracting the largest May crowds at IMS, has presented bands such as Journey, Lynyrd Skynyrd and ZZ Top since shifting from a Thursday to a Friday on the track's calendar in 2005.

Long-running Carb Day attendees said the revelry won't stop.

Paul Bush launched his unbroken streak of attending Carb Day festivities in 1990, when he was a student at Northwest High School.

"I'll still be there this year," said Bush, mentioning a specific tree in Pagoda Plaza where 30 to 40 friends gather each Carb Day.

With the REO Speedwagon-Styx show deleted from the schedule, Carb Day will feature its traditional track activity of the final Indy 500 practice, Pit Stop Challenge and Indy Lights Freedom 100 race.

"I'll meet some of our people up in the stands. But they have those big screens right behind the Pagoda, so you don't even really have to leave anymore," Bush said of his Carb Day routine. "We get the shade from the tree and watch on the screens."

Bush said classic rock bands hired to play Carb Day in recent years haven't coaxed him to walk from Pagoda Plaza to the temporary stage inside Turn 4.

"To me, it seems like Carb Day is the last thing they worry about," he said. "They get Luke Bryan for Legends Day and they spend all this money for Snake Pit acts on Race Day. Then whatever scraps are left over are spent on the Carb Day groups."

The revised Carb Day date of Aug. 21 coincides with a previously scheduled Guns N' Roses show scheduled at Lucas Oil Stadium.

Ben Davis High School alum Jason Jenkins, co-founder of the Pavilion at Pan Am venue, plans to continue his tradition of attending Carb Day.

"I don't think it will affect attendance too bad," Jenkins said. "It's a nostalgic time to connect with friends I haven't seen in a long time.'

Refunds will be available for tickets purchased for the Carb Day (originally scheduled May 22), Legends Day (May 23) and Snake Pit (May 24) concerts. Indianapolis Motor Speedway also will offer credit for any track event, including the Indianapolis 500 in August.

Legends Day at the track has showcased an A-list country concert each year since 2014. Jason Aldean, Florida Georgia Line, Blake Shelton, Keith Urban, Sam Hunt and the Zac Brown Band headlined the Saturday afternoon show.

Meanwhile, one country concert is staying put on the Indianapolis Motor Speedway schedule. FGL Fest, featuring Florida Georgia Line, Dustin Lynch and Riley Green, won't be altered by IndyCar's GMR Grand Prix joining the July 4 lineup at the track.

With the Grand Prix shifting from May 9, Independence Day festivities now include a NASCAR Xfinity Series race, the GMR Grand Prix and FGL Fest.
