Those who already bought the ticket can change their tickets in the evening of the concert at the Jäähalli box office. Porcupine Tree will play also in Tampere the following day. The opening act for both concerts will be Finnish band Hidria Spacefolk. The band's only concert in Finland so far was at Ilosaarirock Festival last summer.
The English band is one of the most acclaimed progressive rock bands to come up in the last 20 years. Lead by guitarist Steven Wilson, Porcupine Tree has released 12 albums. The last one, Fear of a Blank Planet, released last spring, features the guest appearances of Rush guitarist Alex Lifeson and legendary King Crimson leader Robert Fripp.
