Aerial Boundaries

Wikipedia dates the release to July 2, 1984 (catalogue WH-1032), Qobuz to June 18. Much of it was recorded direct to two-track: tracks one to four and six at Windham Hill in West Townshend, Vermont, using a remote truck, track five at Sheffield Studio in Baltimore, track seven at Peabody Electronic Music Studio, track eight at Mobius Music in San Francisco, mixed at A&M Studios in Los Angeles, and track nine at Different Fur Studio in San Francisco. Hedges plays mostly the D-28, with Michael Manring on fretless bass on two tracks and Mindy Rosenfeld on flute on one. It includes his cover of Neil Young's "After the Gold Rush". The liner notes tell the story of the telescope's invention and dedicate the music to the spirit of Galileo. "Spare Change" took 111 hours over a week in Baltimore, combining guitar recordings including tape played backward at different speeds.

The official site says it is his most commercially successful album, with 24 weeks on Billboard's jazz chart. It was nominated at the 27th Grammys for Best Engineered Recording, Non-Classical. S. Victor Aaron in Something Else! called it the record that changed the game for both new age and solo acoustic guitar music, and AllMusic's Daniel Gioffre gave five stars.
