Finnish cello rockers APOCALYPTICA have decided to officially release "Psalm", a beautiful new song which APOCALYPTICA's Perttu Kivilaakso played during the band's most recent tour. In addition, APOCALYPTICA's Paavo Lötjönen has produced the atmospherically dense accompanying music video, which was filmed at the Sibelius Academy, where the band recorded its first album. Paavo took care of everything — from direction to post-production — during the making of the clip, which can be seen below.For the first time in its career, APOCALYPTICA will go on tour with a classical orchestra. The collaboration with the prestigious Finnish Avanti! Orchestra will feature instrumentally performed APOCALYPTICA songs, specially arranged for the band, and the 25-piece orchestra. The long-cherished project will be premiering live in Finland in March 2014. Following the shows in Finland, the tour will proceed to Russia, Germany, Poland, Belarus and the Baltic states. Pre-sales for these unique live events will commence from May 23. For more information, visit Apocalyptica.com. APOCALYPTICA's latest album, "7th Symphony", sold around 13,000 copies in the United States in its first week of release to debut at position No. 31 on The Billboard 200 chart. The majority of the album was produced by Joe Barresi (TOOL, QUEENS OF THE STONE AGE, BAD RELIGION), with two other songs produced by Howard Benson (MY CHEMICAL ROMANCE, MOTÖRHEAD, PAPA ROACH).
