Al McKay co-founded Earth, Wind & Fire in the early 1970s and established himself as one of funk music's most inventive guitarists and arrangers. His contributions to the band's signature sound—layered horn sections, intricate rhythmic grooves, and genre-blending arrangements—made him instrumental in Earth, Wind & Fire's rise to international prominence. McKay's approach to composition and orchestration influenced generations of musicians working across funk, R&B, and pop.
For choral educators, McKay's work represents a masterclass in how complex rhythmic and harmonic ideas can energize an ensemble while remaining accessible to young singers. His sensibility carries through in arrangements like this one, where the core groove remains unmistakable even as it's adapted for voices.
