Nearly every day, new special effects burst onto the music scene, each one expanding the sound of rock 'n' roll. Join us as we explore how new effects, developed in recording studios and in the homes of producers, transformed today's popular music, from bouncing echoes off tiled-bathroom walls to stretching tape tracks to sampling any sound ever recorded. Interviews with top music producers, historians, and performers such as Andy Summers and Moby take us through decades of new innovations that expanded musical boundaries.
