1976 was a big year for The Supremes. With the exquisite Susaye Greene in the group, the line-up sparkled with vitality and pizazz like never before. High Energy was a hit album that firmly ensconced the trio as disco mavens worthy of their moniker. It spawned their last Top 40 hit, "I'm Gonna Let My Heart Do The Walking," and its title track became an anthem in discos and clubs all over the world. Susaye's crsip, brilliant five octave range was displayed in all its glory on this track. The Supremes also became one of the first groups in history to shoot a music video for an album track. This song still makes me want to get up and dance. You just can't sit still when it cranks down and amps up.
