Royal Machines, the self-described “rock’s greatest all-star band,” will perform in concert with special guests following the Acura Grand Prix of Long Beach’s racing events (approximately 6 p.m.) on Saturday, April 9.

The band has a rotating group of recording artists in its roster, though it will be anchored at the post-race event by vocalist Mark McGrath (Sugar Ray), guitarists Dave Navarro (Jane’s Addiction, Red Hot Chili Peppers) and Billy Morrison (Billy Idol, the Cult), vocalist Donovan Leitch, bassist Chris Chaney (Jane’s Addiction) and Long Beach  drummer Josh Freese (Sting, the Replacements).

“There’s nothing more exciting than the sound of Indy cars roaring down the city streets, and my band looks forward to adding our own cacophonous sound to the after party,” said McGrath in a statement. The vocalist competed in the Toyota Pro/Celebrity race in 2015, finishing in eighth place.

The band’s members have included many recording artists in its eight-year existence, including Long Beach drummer Josh Freese. The group performs covers of rock classics as well as songs from their own bands, often bringing special guests up to the stage.

The concert will take place on the Terrace Theater Plaza and, while it’s free for the day’s ticket-holders, attendance will be on a first-come basis. Tickets are on sale for the race weekend, April 8-10 at gplb.com  or by calling 888-827-7333. General admission tickets for Saturday are $74.
