Traffic's first two hit singles, "Paper Sun" and "Hole in My Shoe". Other acts used a Coral electric sitar, designed by American guitarist Vinnie Bell and manufactured by the Danelectro guitar company. Bell's 1967 album Pop Goes the Electric Sitar added to the collection of what Brend terms "sitarploitation" LPs – containing raga rock-style cover versions of well-known pop songs – a phenomenon that, inaugurated by Rao's Raga Rock, also included Sitar Beat and Lord Sitar by Big Jim Sullivan. Consolidation and decline Further examples of the subgenre in 1968 were the Rolling Stones' "Street Fighting Man", with its use of tambura and shehnai over distorted acoustic rhythm guitars, and Harrison's final Indian-style composition for the Beatles, "The Inner Light", which he recorded in January with Indian classical musicians in Bombay. These Bombay sessions also yielded part of Harrison's first solo album, a raga rock soundtrack to the 1968 film Wonderwall, titled Wonderwall Music. Music journalist Chris Ingham has noted Wonderwall Musics influence on the later raga rock sound of 1990s indie band Kula Shaker. In addition to using Indian elements in their single "Dark Star", Garcia's band the Grateful Dead incorporated raga rock, among several other styles, into the extended jams they performed in concert in 1968. According to Echard, the raga rock trend was largely over by early 1968, having declined late the previous year. In Bellman's opinion, the musical exploration evident in raga rock over 1965–67 was largely replaced by a formulaic approach in 1968. He cited the Moody Blues' July 1968 release In Search of the Lost Chord as a work that combined the now-familiar sounds of sitar and tabla with an album-wide concept that reinforced the perceived connection between LSD and Transcendental Meditation (TM), following the Beatles' and Donovan's public endorsement of TM guru Maharishi Mahesh Yogi. 1970s and beyond From 1969 and through the early 1970s, the British progressive rock band Quintessence mixed elements of Indian classical music with rock and jazz. Ananda Shankar (a nephew of Ravi Shankar) released his self-titled album in 1970, a raga rock work that blended sitar with Moog synthesizer. Later in the decade, guitarist John McLaughlin and his band Shakti introduced a jazz-influenced version of raga rock over the course of three albums. In the 1990s, the British indie rock group Cornershop began to assimilate Asian instruments such as the sitar and dholki into their music, culminating with
