Swedish death metallers INSISION will celebrate their 15-year anniversary with the release of "15 Years Of Exaggerated Torment", a 23-song collection containing material from their first demo, 1998's "Meant To Suffer"; a recording of the band's second live appearance in 1998, "Live Like A Worm"; the 1999 mini-CD "The Dead Live On"; 2000's "Promo 2000" demo; 2001's "Revelation Of The SadoGod" demo; plus a newly re-recorded version of an old track. Due on May 25 in the U.S. and June 1 in Europe via Sevared Records, the double-CD set was once again completed with the help of engineer Anders Eriksson at Off Beat Studio in Stockholm. The cover art was created by Rian from Indonesia and can be seen below.Commented the band: "We feel proud to have stayed solid throughout these years. "Right now we're working hard to create new songs for the upcoming full-length CD, which hopefully will be our strongest release to date. We don't have a recording date settled, but as soon as eveything falls into place and feels dark'n'fast enough, we will start recording. All credits to the loyal fans of death metal who supported INSISION through these 15 years. Death metal is our religion." INSISION previously described its new material as "a mix of the complex stuff we did on our first record, 'Beneath The Folds Of Flesh' back in 2001 along with rhythm parts that can be explained with a more darker approach." INSISION's "End Of All" EP came out last year via Sevared.
