METALLICA is expected to play the song "Frayed Ends Of Sanity" live in its entirety for the first time at tonight's (Wednesday, May 28) Sonisphere festival in Helsinki, Finland. For years, METALLICA has teased the track in a variety of ways throughout the set, but quickly abandoned it, veering sharply into something else."We're going to have sit down and spin that one around for an hour or two," METALLICA drummer Lars Ulrich told the Delaware County Daily Times of "Frayed", which remains the only song over the first five albums that the band has never performed live in its entirety. "We carry a rehearsal room with us wherever we go. Give us an hour and we can learn any song in our catalog. We like to make the setlist real wacky and change it up as much as possible, but in 2014 the fans are picking the songs." METALLICA recently completed a South American tour where the band played a nearly all-request set, with 17 songs chosen online by fans prior to each gig and the last slot filled by the new track "Lords Of Summer". That song or possibly another new one will also feature in the set list for the band's European festival run, on which it will repeat the "by request" format. "It certainly gives me butterflies in the stomach in a good way, and I think it should be a lot of fun for the fans," Ulrich said after announcing "Metallica By Request" last year. "This at least puts a stop to the whining about the set list because it's basically the fans that are picking it." METALLICA's "by request" show in South America featured such non-rarities as "Master Of Puppets", "Welcome Home (Sanitarium)", "Battery", "Fade To Black", "One" and "Enter Sandman". "To be totally honest with you, sometimes I wish they would vote on some of the really obscure songs. We love playing crazy stuff," Ulrich told Delaware County Daily Times. METALLICA spent some time this spring working on material for the follow-up to 2008's "Death Magnetic", but the band's 10th studio album is not expected out until 2015.
