His distinct charm is an irresistible blend of soul, jazz, and pop influences. He possessed phenomenal songwriting prowess, smooth vocal performances, was both a great soul guitarist and dextrous keyboard player and known for genius chord progressions. It all added up to a multi-layered brilliance entering the studio, and the singular sound he landed on was laced with soulful, sweeping strings and funky horns, touching lightly on disco, while allowing his supple voice to carry the stunning tracks he'd crafted. String-swept opener Special To Me immediately sets the tone with its lush instrumentation, rich harmonies, and Caldwell's velvety-smooth vocals.
