Bruce Springsteen and the E Street Band have postponed four European shows as Springsteen deals with “vocal issues.”

Springsteen is “recuperating comfortably,” according to the Boss' social media.

Concerts May 28 at the Letnany Airport in Prague and June 1 and 3 at the San Siro Stadium in Milan have been postponed, according to an announcement on Springsteen's socials on Sunday, a day after he postponed a May 25 performance in Marseille, France.

“Following yesterday's postponement in Marseille due to vocal issues, further examination and consulting has led doctors to determine that Bruce should not perform for the next ten days,” the statement read. “With this in mind, additional postponements are required for Airport Letnany in Prague (originally scheduled for May 28) and San Siro Stadium in Milan (originally scheduled for June 1 and 3).

"New dates for these shows will be announced shortly. Those wishing a refund will be able to obtain it at their original point of purchase. Bruce is recuperating comfortably, and he and the E Street Band look forward to resuming their hugely successful European stadium tour on June 12 in Madrid at the magnificent Civitas Metropolitan.”

Bruce Springsteen setlist 2024:Every song he sang at world tour relaunch in Phoenix

Springsteen postponed multiple shows last year during a bout with peptic ulcer disease. The 24 postponed performances have been rescheduled, and more stadium dates in Europe and two shows in the U.S., have been added.

The strength of Springsteen's voice has been noted by fans since the E Street Band's tour resumed March 19 at the Footprint Center in Phoenix. The Asbury Park Press wrote that there “were sweetly sustained notes on 'Letter to You,' core-rocking earthy growls on 'Seeds,' and majestic intonations on 'The Promised Land' “ at the April 12 concert at Mohegan Sun Arena in Uncasville, Connecticut.

Springsteen and the E Street Band last played May 22 at the Stadium of Light in Sunderland, England, in what reports called a chilly and rainy day. The Boss also sang “Thunder Road” when he received an Ivor Novello Award for songwriting on May 23 in London. The BBC said his voice was “hoarse and squeaky” at the ceremony.

“We came out last night, and I was like, 'What is this weather? Driving rain, wind roaring,’ ” Springsteen said at the event. “But standing in front of me, in the rain, I realized: These are my people.”
