Betty Baker and The Jaxsis were a notable rhythm and blues band prominent in the late 1960s. Led by charismatic vocalist Betty Baker, the band was known for blending traditional blues elements with a distinct pop sensibility, resulting in a crossover appeal that significantly impacted the music of the era. The Jaxsis' tight instrumental work, particularly the guitar work of Jim "Jax" Jackson, was a defining feature of their sound. Their most influential work, the album "Blues in the City," is still considered a benchmark in rhythm and blues music.
