This week, ambient heavyweight Tim Hecker releases his second album of the year, Dropped Pianos.

Rather than a full new Hecker album, Dropped Pianos is designed as a companion piece to the other album he released this year, Ravedeath, 1972, collecting nine “piano sketches” that Hecker recorded in 2010 as he drew up ideas for Ravedeath. Altered Zones are now streaming the record in full; you can listen to it via the Soundcloud widget below.
