Although the prime exponents of the '70s California soft rock style were album artists such as America, Bread, and Poco, Seals and Crofts--essentially an AM singles band--have aged even better. The key is in their tight songwriting."Summer Breeze,""Diamond Girl," and the rest of the hits display an odd, but apt, sense of arrangement and instrumentation--and enough of a rock & roll sensibility to keep their sound from slumping into period piece laid-backism. Case in point: The duo's first band was the Champs, noted for the fake-Latin crudhopper"Tequila." Even so, it's not grit, but ace songcraft that captures the prize here. All of the ace songs are included.
