Dream Theater turns 40 and is heading for a big tour to celebrate the anniversary, the European days of which will be published today. The An Evening With Dream Theater 40th Anniversary Tour also arrives in Finland, where the band will be seen at Espoo’s Metro Areena on November 6.

The tour starting in October is meaningful for the band in many ways, and a special reason for joy is Dream Theater traveling again in the lineup from 14 years ago, with drummer Mike Portnoy returning to the band’s ranks alongside James LaBrie, John Myung, John Petrucci and Jordan Rudess. Portnoy and the rest of the band parted ways after the Black Clouds & Silver Linings album released in 2009, so today’s tour news has been long awaited.
