They played at notable festivals, such as the Crystal Palace Garden Party in London, where they introduced their quadraphonic sound system, creating an immersive experience for the audience.In addition to "Meddle," Pink Floyd released the single "One of These Days," which became a staple in their live performances due to its high energy and driving rhythm.
