***1/2

Young electronicist Tucker Martine is one of the most enigmatic characters in Seattle's new music scene. In Wayne Horvitz's 4+1 Ensemble, as in a recently released session with free-jazz statesmen Sam Rives and Julian Priester, he hovers in the background, capturing, warping, and quietly reinjecting the sounds of his fellow players back into the mix. "Mount Analog" is, with the inclusion of some outside help on some tracks, his solo project. Martine's music is even more ghostlike on this record; each piece seems to hint at experiences from the past, from the subconscious, from other music. Field recordings, keyboards, subterranean rumblings, guimbri, violins, typewriters, harmonium, AM radio, surfacing creatures of deep, electronics, children at play, treatments, drums, and bass are here artfully woven by Mount Analog into magnificently subtle mediations on the prehistory of the digital age.
