Meddle

'Meddle' serves as a pivotal transitional album, capturing the band's collective and experimental creative process after their early psychedelic phase and before the conceptual, Roger Waters-led era. Its first side features a diverse set of individual tracks, from the menacing, dual-bass instrumental "One of These Days" to the gentle, acoustic "A Pillow of Winds." The album is defined by the side-long, 23-minute composition "Echoes," a sonic exploration built from studio experiments like Richard Wright's iconic piano 'ping' effect, which established the sprawling, atmospheric soundscapes that would become a hallmark of the band's masterpieces.
