Late next month prog legends King Crimson hit the road for their first full U.K. tour in 33 years. Earlier today the band revealed what material fans can expect to hear on the tour.

Not only will King Crimson perform songs from their back catalog dating back to 1969, but they will also unveil newly written, previously unheard material. Last year the band embarked on their first U.S. tour since 2008 and focused on material from King Crimson’s ’70s era.
