Indie quintet The Great Spy Experiment made history this week, when their new English-language album became the first by a home- grown band to top an iTunes Store download chart.Litmus was released on Monday and peaked at No. 1 on the album download charts of the Singapore version of iTunes, tech giant Apple's online music and entertainment store.The top spot has since been traded among Litmus, local Mandopop star JJ Lin's Stories Untold, and Korean boyband SHINee's Dream Girl - The Misconceptions Of You.Spy's frontman Saiful Idris, 33, however, was modest about the achievement, reports The Straits Times."We have to put it in perspective," he says of their sophomore effort released by home-grown label Riot! Records and distributed by Universal Music Singapore."We are happy, but we understand from Universal that the Singapore iTunes store has been around for only six months. If you look at it that way, there hasn't been many local bands who have released albums. You can say we are the first but I don't think it means all that much." The Singapore iTunes Store, which sells digital music, movies and TV shows, was launched in June last year.The singer and guitarist adds: "It still feels good to see your work alongside people such as Adele and Justin Timberlake and Jay Chou though."Physical CD copies of the album also started selling on the same day at music stores such as HMV and Gramophone. According to Universal, 1,000 copies were pressed. Universal was unable to provide sales figures for both the downloads as well as CD copies, saying that it is too early to tell.The band, which also comprise drummer/singer Fandy Razak, 33; guitarist Song, 38; keyboardist Magdelene Han, 36; and bassist Khairyl Hashim, 36, are a popular name in the indie gig circuit. They have played at major local music events such as Baybeats and SingFest, as well as overseas in the United States, Australia and France.Universal Music Singapore's marketing director Lim Teck Kheng says The Great Spy Experiment have "set a milestone". "It shows that if a band has talent and spends time working on the ground, playing a lot of gigs, support from the fans will come."
