British rockers Radiohead are buckling under the strain of writing their new album - their first in three years. Frontman Thom Yorke has posted an emotionally-charged message on the band's website, admitting the recording sessions feel like a long dark tunnel with no end. He says, "I've been tearing my hair out. Today, myself, I was struggling. Feels like we been trapped for a long time in la la land. "Furiously writing, working out parts. Cracking up. Not much time left. Unsure about everything. "I'm not supposed to put any of this here. So that's why I am." The group's seventh album is due out this summer (06) and they have plans for a major tour.
