Texan duo Jim Seals and Dash Crofts were kings of ’70s pop, ruling the radio with a cool, breezy sound that would retrospectively make them yacht-rock icons to a new generation in the 21st century. The wider world’s introduction to Seals & Crofts was the 1972 smash “Summer Breeze,” as perfect an evocation of a sweet, lazy, sunbaked day as American pop ever produced. The duo’s sleek harmonies and hook-heavy mix of folk, pop, rock, and R&B influences helped define the decade with similarly sunny evergreens like the gently swinging “Diamond Girl” and the tender, twinkling love call “Get Closer.”
