R.E.M.'s 15th studio album "Collapse Into Now" comes out March 8th and guitarist Peter Buck thinks it could be their best album ever.

The new album will feature guest appearances by Pearl Jam singer Eddie Vedder, Patti Smith and Peaches.

Buck told "NME" magazine, quote, "I've always tended to not say it's the greatest record we've ever done because that's what everyone does and it's usually bull crap.  But this feels like every song all the way through is great.

"That's just the feeling.  It's got some beautiful, heartbreaking things as well as some really noisy rock and everything in between.  It sounds really classic."
