Passage: The first single released from Mona Bone Jakon was "Lady D'Arbanville", which Stevens wrote about his young American girlfriend Patti D'Arbanville. The record, with a madrigal sound unlike most music played on pop radio, with sounds of djembes and bass in addition to Stevens' and Davies' guitars, reached number 8 in the UK. It was the first of his hits to get real airplay in the US. It sold over 1 million copies, and was awarded a gold record in 1971. Other songs written for D'Arbanville included "Maybe You're Right", and "Just Another Night". In addition, the song "Pop Star", about his experience as a teen star, and "Katmandu", featuring Genesis frontman Peter Gabriel playing flute, were featured. Mona Bone Jakon was an early example of the solo singer-songwriter album format that was becoming popular for other artists as well. Rolling Stone magazine compared its popularity with that of Elton John's Tumbleweed Connection, saying it was played "across the board, across radio formats".Mona Bone Jakon was the precursor for Stevens' international breakthrough album, Tea for the Tillerman, which became a Top 10 Billboard hit. Within six months of its release, it had sold over 500,000 copies, attaining gold record status in the United Kingdom and the United States. The combination of Stevens' new folk rock style and accessible lyrics which spoke of everyday situations and problems, mixed with the beginning of spiritual questions about life, would remain in his music from then on. The album features the Top 20 single "Wild World"; a parting song after D'Arbanville moved on. "Wild World" has been credited as the song that gave Tea for the Tillerman 'enough kick' to get it played on FM radio; and the head of Island Records, Chris Blackwell, was quoted as calling it "the best album we've ever released". Other album tracks include "Hard-Headed Woman", and "Father and Son", a song sung both in baritone and tenor, about the struggle between fathers and their sons who are faced with their own personal choices in life.
