Jelly Roll may sing the song “Save Me” … but, Saturday night he’s giving back to people who ran headlong into danger to save L.A. amid the recent devastating wildfires — putting on a benefit concert for first responders and their families … TMZ has learned.

Multiple sources tell us mass emails have already been sent to several SoCal fire departments and law enforcement agencies — including the National Guard … giving them until midnight tonight to request tickets for the once-in-a-lifetime show. To be clear: the show is only for first responders and their guests … no general admission.

A source with direct knowledge tells TMZ … the event is not a fundraiser … Jelly Roll is putting on the concert out of the kindness of his heart to thank all the first responders who’ve worked tirelessly to battle the deadly wildfires.

The event just went live on Ticketmaster … offering first responders in L.A. up to four tickets for themselves and friends or family to watch the artist, and his unnamed “friends,” perform at the Rose Bowl on Feb 1.

Obviously, Jelly Roll’s concert isn’t the only show with a connection to the devastating wildfires in Los Angeles earlier this month … ’cause FireAid — the benefit concert for victims of the L.A. wildfires — is taking place at Intuit Dome and the Kia Forum Thursday in Inglewood.

Jelly Roll’s playing that show too … a pretty hectic week for the star who clearly wants to help Angelenos get back on their feet after the tragic natural disaster.
