The Radiolarian Series is an album project by experimental jazz fusion trio Medeski Martin & Wood released in three installments in 2008–2009. The project is atypical among studio albums because, in a reversal of the typical recording process, the band decided to compose and then develop the songs through a series of tours before recording the music in the studio. "The problem with us," keyboardist John Medeski explains, "is that when we record an album, by the time a record company gets it out, we’ve already been playing the music for six or eight months, and we’re ready to move on."
