The band is dealing with repercussions from a May 22 bus crash and has been forced to cancel all U.S. appearances through September.

Speaking from a hospital in London where he was airlifted May 24, singer Dryden Mitchell said, “I’m just so grateful that my injuries aren’t worse. There will be a lot of rehabilitation and physical therapy, but I’m planning on working hard so the band can get back to writing songs, and then we can get in the studio and record the new album as soon as possible.”

Mitchell sustained the most serious injuries of the band members. He fractured his C2 vertebra, which will likely require surgery. Initial treatment has involved traction and the use of a metal halo to keep his upper body immobile.

Mitchell’s bandmates Terry Corso and Tye Zamora both sustained injuries to their ankle or foot, while Mike Cosgrove escaped with cuts and bruises.

In addition to the band members, five crew members were present in the bus during the accident. Their injuries ranged from broken ankles, broken feet and back injuries to simple cuts and bruises.

The most seriously injured of the crew is the band’s security head and personal assistant, David Zajic. The Czech citizen was airlifted to Prague, where he is listed in critical condition. He is being treated for multiple skull and facial fractures, which are expected to require reconstructive and plastic surgery. “We are extremely concerned about David,” said Mitchell. “He’s our best friend and we’re praying for a full recovery.”

The accident happened near Navalmoral de la Mata, Spain, west of Madrid, as the band was en route to its scheduled concert in Lisbon, Portugal. Reports indicate the bus collided with a parked truck shortly after 2:00 a.m. However, Spanish news agency Efe said the bus rear-ended the truck on the approach to a mountain tunnel.

The bus driver, Christopher Holland of Wales, was killed on the scene. According to Spanish news reports, the driver of the truck was only slightly injured.
