OK, here’s an intense concept compilation: 99 tracks, each exactly 45 seconds long. How does this work as an album? By assembling tracks by several dozen little known experimental artists, including many whose click-and-glitch style is made for the short of patience. Within this, you have a dauntingly diverse collection of sounds, grooves and experiments, reminiscent of an old Negativland album. There are few names to note: DJ Spooky and Silver Apples make contributions, but otherwise, who knows? Never boring, because nothing lasts that long. Mostly mellow, mostly instrumental, open-minded music you will probably never hear elsewhere. The bedroom-studio generation speaks.
