"Rain" is the upcoming second single from Mika's second studio album The Boy Who Knew Too Much to be released in the United Kingdom. The song was produced and mixed by Greg Wells and features the violinist Owen Pallett.
“ ["Rain"] is an unapologetic '80s pop record. I bumped into producer Stuart Price while he was working with The Killers at Olympic Studios. He helped me program this. It reminded him of ABBA and Frankie Goes To Hollywood. ”
—Mika, Q Magazine
The music video for "Rain" was filmed in Epping Forest in Essex and premiered online on 16 October, 2009. It was directed by Nez Khammal. The video is set in a dark enchanted forest with Mika waking up in a colourful tent. He is soon joined by various strangely dressed imps and creatures who dance around him at first but chase him out of the forest amid exploding fireworks.
