Jeff Beck has been forced to cancel his European tour in order to receive “emergency medical attention.”

Beck was scheduled to begin the second leg of his tour in Austria on Thursday (June 27), but the legendary guitarist has been advised by his doctors not to perform for the next six weeks.

“It is with the greatest regret that Jeff Beck has been forced to cancel the forthcoming European dates of his worldwide tour, set to begin in Austria on 27 June,” reads the statement on Beck’s official website. “Following many months of international touring and after seeking emergency medical attention, Jeff will now undertake a short hospital procedure and his doctors have instructed a complete break from performance for a total of six weeks. Following the treatment, Jeff will fulfil his US tour commitments beginning in Missoula MT on 8 August.”

The statement continued: “He sends his profound apologies to those fans who had bought tickets for the European concerts and very much looks forward to playing for his American audiences after he has completed his treatment.”

The singer will begin his month-long co-headlining US tour with ZZ Top in Missoula, Montana, on August 8, where the band will perform a collaboration at the end of each night’s show.
