Radiohead vows checks after shows quickly sell out

Radiohead pledged Friday to put in place extra measures to prevent scalping after tickets for the arthouse rockers' upcoming tour quickly sold out.

Radiohead frontman Thom Yorke commiserated with fans over social media after tickets to the 11-date tour of major arenas sold out in minutes.

The band warned that venues would scrutinize many tickets at the door, ejecting people without identification that matches the listed names.

"Strict rules are in place to try and reduce online touting, but inevitably some will find their way onto secondary ticketing sites at inflated prices," the band said in a statement.

"We hope you understand the need to put such measures in place to give more fans a chance to get to the shows," it said.

Tickets to Radiohead's shows at Madison Square Garden in New York were already fetching into the thousands of dollars on resale sites, far above list prices.

Radiohead is only playing five cities on the tour -- Amsterdam, London, Los Angeles, New York and Mexico City -- although the band is also performing at eight festivals around the world.

Ticket scalping has long alarmed musicians and fans, but with few easy solutions to curb the inflated prices.

Prince has been among the most aggressive in addressing the scourge by announcing shows at the last minute and, most recently, not issuing physical tickets at all, instead keeping names at the door.

Radiohead has long been critical of the commercial structures of the music business and has looked for alternative ways to release albums.

The band is widely expected soon to release a ninth album, the first since 2011's "King of the Limbs" which Radiohead sold on its own.
