1970s the next generation of British artists added new tunings and techniques, reflected in the work of artists like Nick Drake, Tim Buckley and particularly John Martyn, whose Solid Air (1972) set the bar for subsequent British acoustic guitarists. Perhaps the most prominent exponent of recent years has been Martin Simpson, whose complex mix of traditional English and American material, together with innovative arrangements and techniques like the use of guitar slides, represents a deliberate attempt to create a unique and personal style. Martin Carthy passed on his guitar style to French guitarist Pierre Bensusan. It was taken up in Scotland by Dick Gaughan, and by Irish musicians like Paul Brady, Dónal Lunny and Mick Moloney. Carthy also influenced Paul Simon, particularly evident on Scarborough Fair, which he probably taught to Simon, and a recording of Davy's Anji that appears on Sounds of Silence, and as a result was copied by many subsequent folk guitarists. By the 1970s Americans such as Duck Baker and Eric Schoenberg were arranging solo guitar versions of Celtic dance tunes, slow airs, bagpipe music, and harp pieces by Turlough O'Carolan and earlier harper-composers. Renbourn and Jansch's complex sounds were also highly influential on Mike Oldfield's early music. The style also had an impact within British folk rock, where particularly Richard Thompson, used the D–A–D–G–A–D tuning, though with a hybrid picking style to produce a similar but distinctive effect. "New Age" approach In 1976, William Ackerman started Windham Hill Records, which carried on the Takoma tradition of original compositions on solo steel string guitar. However, instead of the folk and blues oriented music of Takoma, including Fahey's American primitive guitar, the early Windham Hill artists (and others influenced by them) abandoned the steady alternating or monotonic bass in favor of sweet flowing arpeggios and flamenco-inspired percussive techniques. The label's best selling artist George Winston and others used a similar approach on piano. This music was generally pacific, accessible and expressionistic. Eventually, this music acquired the label of "New Age", given its widespread use as background music at bookstores, spas and other New Age businesses. The designation has stuck, though it was not a term coined by the company itself. Percussive approach "Percussive fingerstyle" is a term for a style incorporating sharp attacks on the strings, as well as hitting the strings and guitar top with the hand for percussive effect.
