2009, Fripp recommended that Guitar Craft cease to exist on its 25th anniversary in 2010. On 1 September 2022 Fripp published The Guitar Circle, a book of writings concerning Guitar Craft. Soundscapes Fripp returned to recording solo in 1994, using an updated version of the Frippertronics technique that creates loops employing digital technology instead of analogue tapes. Fripp has released a number of records that he called "soundscapes", including 1999, Radiophonics, A Blessing of Tears, That Which Passes, November Suite, The Gates of Paradise, Love Cannot Bear and At the End of Time, as well as numerous download-only live recordings. (The sampler Pie Jesu consists of material compiled from A Blessing of Tears and The Gates of Paradise.) 1990s collaborations with David Sylvian and others Fripp's collaborations with David Sylvian feature some of his most exuberant guitar playing. Fripp contributed to Sylvian's twenty-minute track "Steel Cathedrals" from his Alchemy: An Index of Possibilities album of 1985. Then Fripp performed on several tracks from Sylvian's 1986 release, Gone to Earth. In late 1991, Fripp had asked Sylvian to join a re-forming King Crimson as a vocalist. Sylvian declined the invitation, but proposed a possible collaboration between the two that would eventually become a tour of Japan and Italy in the spring of 1992. Also in 1991, Fripp released an album with the project Sunday All Over The World, also featuring his wife Toyah Willcox, former League of Crafty Guitarists member Trey Gunn on Chapman Stick, and drummer Paul Beavis. The prior name of this band was Fripp Fripp, and they toured as such in 1988. They renamed to SAOTW, and toured again as SAOTW, in 1989. In July 1993, Sylvian and Fripp released the collaborative effort The First Day. Other contributors were soon-to-be King Crimson member Trey Gunn on Chapman Stick and Jerry Marotta (who, like Sylvian, almost became a member of King Crimson) on drums. When the group toured to promote the CD, future King Crimson member Pat Mastelotto took over the drumming spot. The live document Damage was released in 1994, as was the joint venture, Redemption – Approaching Silence, which featured Sylvian's ambient sound sculptures (Approaching Silence) accompanying Fripp reading his own text (Redemption). During the early and mid-1990s Fripp contributed guitar/soundscapes to Lifeforms (1994) by the Future Sound of London and Cydonia (released 2001) by the Orb, as well as FFWD, a collaborative effort with the latter's
