"One of These Days" is the opening track from Pink Floyd's 1971 album Meddle. The song is instrumental except for a distorted, low voice that says "One of these days I'm going to cut you into little pieces" and features double-tracked bass guitars played by David Gilmour and Roger Waters. Waters' bass is panned hard left with Gilmour's fading into the right channel. 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.
