"One of These Days" is the opening track from Pink Floyd's 1971 album Meddle.[1][2] The composition is instrumental except for a distorted, low voice that says "One of these days I'm going to cut you into little pieces" (spoken by drummer Nick Mason, a rarity for the band) and features double-tracked bass guitars played by David Gilmour and Roger Waters,[2] with each bass hard panned into one channel of stereo. Gilmour's bass sound is quite muted and dull. According to Gilmour, this is because that particular instrument had old strings on it, and the roadie they had sent to get new strings for it wandered off to see his girlfriend instead.[3]
