Rock band ZZ Top have cancelled their European tour to let a band member have treatment for an ear ailment.
ZZ Top performed at the VH1 Rock Honors in Las Vegas on Saturday
Bassist and singer Dusty Hill needs treatment for a benign growth in his inner ear.
The tour was due to start on 15 June in Leipzig, Germany, and finish in Norway in early July.
Preliminary plans for his treatment do not include surgery so US concerts, due to start in Dallas on 15 July, are still expected to go ahead.
"I'm looking forward to dealing with this problem and getting back out there with Billy and Frank," Hill said. "I'm sure we'll put this behind us very shortly."
In a statement, Hill's otolaryngologist Dr Shawn Nasseri said: "In the near term, we plan to stabilise Dusty's hearing and symptoms with medication and a conservative management strategy."
The trio, who have been together for 38 years, and are known for the guitarists' trademark beards, performed and were honoured at the VH1 Rock Honors in Las Vegas on Saturday.
The cancellation comes seven years after Hill was diagnosed with Hepatitis C.
