Over 25 years ago, five Denver musicians who collaborated with Apples in Stereo, Neutral Milk Hotel, Warlock Pinchers and Dressy Bessy came together to play jazz standards on Tuesday afternoons as the Perry Weissman 3. Still together, the band has played under the moniker PW3 for the past decade. While the musicians originally formed to play jazz on a regular basis, they also started writing original material more in the vein of Chicago instrumental post-rock act Tortoise and German krautrock pioneer Neu! PW3 nods to both on Backlog, the group's new twenty-song, two-hour-long album that’s been two years in the making with producer Kyle Jones.
