Nick Zammuto used to be one half of the Books, but recording on his own, he’s lately moved away from that duo’s arty, theoretical laptop twinkle toward an idiosyncratic rock-band crunch. Zammuto will release Anchor, his new solo album, next week, and the songs we’ve posted from the album — “Great Equator,” “Hegemony,” “IO” — are simply unrecognizable as being the new music from the guy who was in the Books. He’s on to an entirely new page now, and as of today, you can stream all of Anchor over at NPR.

Anchor is out 9/2 on Temporary Residence.
