Lonnie and Floyd were a dynamic American blues duo that emerged in the late 1960s. Known for their fusion of traditional Delta blues with contemporary soul and R&B influences, their music offered a fresh take on the blues genre. Lonnie's raspy, soulful vocals combined with Floyd's virtuosic harmonica playing created their signature sound. Their most influential work, "Blues of the River", released in 1972, is recognized as a seminal contribution to the evolution of modern blues music.
