Cobalt Hour is the third studio album by Yumi Arai, later Yumi Matsutoya, released on 20 June 1975. Backed by the Tin Pan Alley circle and with a chorus of Hi-Fi Set, Minako Yoshida, Taeko Ohnuki and Tatsuro Yamashita, it is often named as the starting point of city pop.[1][2]
Background and recording
Produced by Alfa’s Kunihiko Murai with Shōrō Kawazoe, the album was recorded between 1 March and 25 April 1975 with Haruomi Hosono on bass, Shigeru Suzuki on guitar, Tatsuo Hayashi on drums and Masataka Matsutoya on keyboards, who also edited the arrangements.[1] The single “Rūju no Dengon” was released ahead of it on 20 February 1975.[1]
Release and legacy
The album reached No. 2 on the Oricon LP chart and spent 90 weeks on it, selling 435,000 copies; it was the fifth best-selling album of 1976.[1] Nippon.com’s guide to the genre singles it out for its strong city pop flavour.[2] “Rūju no Dengon” was later used in Hayao Miyazaki’s Kiki’s Delivery Service (1989).[3] The album was remastered by Bernie Grundman for CD in 2000.[1]
