Co-founded by vocalist Noh Salleh and guitarist AG Coco, Hujan became a popular band in Malaysia's independent music scene before finding mainstream success with the 2007 single "Pagi Yang Gelap." The group formed in 2005 in Kuala Lumpur, with bassist Hang Dimas and drummer Azham Ahmad completing the original lineup. A pair of EPs, 1, 2, 3, Go! and Check Check Rock Rock, were both released in 2007, with "Pagi Yang Gelap" becoming one of the year's biggest alternative rock hits in Malaysia. A full-length album, Hujan, followed in 2008. Hujan received five nominations at the Anugerah Muzik Malaysia ceremony in 2009, winning awards for "Best Rock Album" and "Best Song." Mencari Konklusi was released that same year and earned the group another handful of Anugerah Muzik Malaysia nominations, as did 2010's Lonely Soldier Boy. The group continued to tour internationally through the 2010s, with Izzat Uzaini replacing Hang Dimas on bass. Although Hujan's latter-day singles failed to match the commercial success of the band's breakthrough single, "Pagi Yang Gelap," albums like 2012's Sang Enemy and 2016's Jika Sempat helped maintain the band's popularity amongst alternative rock fans in Malaysia, as did the EPs Suria (2018) and Pelangi & Kau (2020).
