Dalbergia Retusa is an extensive double LP selection of the solo guitar music of Hans Reichel, compiled by Oren Ambarchi. Last heard on Black Truffle as one quarter of the joyously anarchic Bergisch-Brandenburgisches Quartett, Hans Reichel (1949-2011) is one of the great figures of experimental guitar music. Though perhaps lesser known than peers like Derek Bailey, Fred Frith and Keith Rowe, Reichel’s rethinking of the instrument was in some ways the most radical of all. Early on, he dispensed with existing guitars to build a series of his own that explored the use of additional strings and fretboards, moveable pickups, extra bridges, special capos, and other innovations documented in the extensive booklet accompanying this release.

Reichel was a long-term resident of Wuppertal, the small Western Germany city that became an unlikely centre of European free jazz in the late 1960s, also home to Peter Brötzmann and Peter Kowald. His solo debut Wichlinghauser Blues was an early entry into the FMP discography and began a relationship with the label that stretched into the 1990s; all the solo performances heard here were first released on FMP. As Reichel says in the charming archival interview with Markus Müller included here, he was ‘always a cuckoo’s egg at FMP’, a label that began as an outlet for roaring European free jazz. What strikes the listener right from the opening selection on Dalbergia Retusa—‘Return of the Knödler show’, from 1987’s The Dawn of Dachsman—is the extraordinary beauty of Reichel’s music, at once alien in the shimmering sonorities and unconventional pitch relationships made possible by his invented instruments, and deeply lyrical, even romantic in its harmonic content. Growing up in West Germany in the 1960s, Reichel’s formative influences were mainly British and American rock bands, a background that shines through in many of the pieces included here: ‘An old friend passes by’ is haunted by the ghost of Hendrix’s rhythm guitar, and the wild closer ‘Heimkehr der Holzböcke’, taken from a rare 1975 7” and the only piece to use overdubbing, layers errant hammer-on and slide tones over a Canned Heat boogie chug.

Reichel was an important source for the development of Oren Ambarchi’s own extended approach to the electric guitar. Appropriately enough, his selection opens with the very first piece by Reichel he ever heard, on a flexidisc included with a 1989 issue of Guitar Player magazine. Though Reichel collaborated with others extensively in many settings and also performed on violin and his other major contribution to instrument invention, the daxophone, his music for solo guitar remains at the core of his oeuvre. Focusing exclusively on solo pieces recorded between 1973 and 1988, the 23 pieces on Dalbergia Retusa showcase the range and consistency of Reichel’s work, allowing the listener to see how his performances developed hand-in-hand with his instrumental inventions. On a piece from his very first LP, played on an 11-string instrument (partly strung with piano strings and using a schnapps glass a slide), we hear his intensive exploration of fret-hammering to create zither-like, chiming tone, which Reichel would hone further in later years with a double fretboard guitar specifically designed to be hammered rather than fretted and picked. On a piece from 1979’s Death of the Rare Bird Ymir, Reichel uses two steel-string acoustic guitars at once, with beautiful results: ‘some even say too beautiful’, he jokes in the interview included here. Many of the pieces from the 1980s make use of varieties of the ‘pick behind the bridge guitar’, instruments of uncanny harmonic richness primarily designed to be played on the ‘wrong’ side of the bridge. At times the unexpected behaviour of attacks, resonance, and decay can almost seem electronic, conjuring up the technology-assisted work of Henry Kaiser or even Fennesz, but realised solely through Reichel’s unorthodox techniques on his invented instruments. Extensively illustrated with photos and Reichel’s own plans and drawings of his instruments, Dalbergia Retusa is an essential introduction to the unique world of Hans Reichel. Rarely has music been at once so strange and so beautiful.
