Two members of the Indie pop band Twin Shadow remain in the hospital after their tour bus hit a tractor-trailer in Colorado on Friday. A dozen people, including the band members, were injured in the crash that occurred between the Twin Shadow bus and country duo Thompson Square’s tour bus.

Singer George Lewis Jr., who goes by the nickname Twin Shadow, will undergo reconstructive hand surgery this week. He said in a statement that drummer Andy Bauer was hospitalized in serious condition, as was the bus driver John Crawford.

No one on Thompson Square’s bus was injured and the duo issued a statement saying their thoughts and prayers were with those who were injured.

Both bands were headed to Denver for shows Friday night, but they were not traveling together.

Dorelle Zahn, the mother of the Twin Shadow's keyboard player Spencer Zahn, told The Denver Post that he texted her to say that he had been in an accident, and he was in pain but conscious.

The crash happened not far from Denver International Airport, where fog was also a problem on Friday. Some smaller regional flight arrivals had to be diverted to Colorado Springs and Pueblo.

Twin Shadow has postponed all tour dates through May 22.
