Ed Miles/Nonesuch RecordsRobert Plant and his current band, The Sensational Space Shifters, postponed two concerts on their current North American tour this week after the singer came down with a case of laryngitis. The affected dates, a June 7 show in Toronto and a June 9 performance in Rochester Hills, Michigan, have been rescheduled for September 15 and September 10, respectively.

In a message posted Tuesday on his official Facebook page, Plant writes, “Sunday morning I woke up with a flu that’s developed into laryngitis. I’m really disappointed as I’ve only missed 1 gig in 15 years and now here’s two in a row. It’s heartbreaking. I’m furious, frustrated and silent.”

Meanwhile, the ex-Led Zeppelin frontman also commented on his illness and the postponed Toronto show in a Facebook note posted on Sunday. “I woke up this morning and found that I had more of a similarity with a crooning Kermit than my normal Golden self, so heaps of apologies,” he wrote. “It’s not my idea of fun to miss a gig.”

Plant and the Sensational Space Shifters’ next concert is scheduled for Wednesday, June 10, in Chicago, and the current trek will wrap up on June 17 in Philadelphia. The postponed shows will sandwich a previously announced appearance at the Lockn’ Festival in Arrington, Virginia, where the band is confirmed to perform on September 12 and 13.
