On this day in music history: May 24, 1975 - “Baby That’s Backatcha” by Smokey Robinson hits #1 on the Billboard R&B singles chart for 1 week, also peaking at #26 on the Hot 100 on June 28, 1975. Written and produced by Smokey Robinson, it is the first solo chart topper for the Motown legend. Following his departure from The Miracles three years earlier, the veteran singer, songwriter, and producer had struggled to establish an identity separate from his role as lead singer of his former group. His first two solo efforts, “Smokey” and “Pure Smokey” released in 1973 and 1974 fair alright on the R&B charts, but fail to make much of an impact anywhere else. One of the ways he evolves his sound is by singing in a lower register than his trademark falsetto tenor voice. Released as the first single from Robinson’s landmark solo album “A Quiet Storm”, it quickly takes hold on R&B radio and crossover to the pop 40 becoming his first solo single to reach that plateau.
