The tracks are taken from 1964 sessions in Los Angeles before the band had inked its contract with Columbia -- or was even called the Byrds. Although not as polished as the albums that followed, these demo tracks go beyond rough tryouts. Most are capable of melding British Invasion energy with folk music of the burgeoning protest era. One new track has David Crosby singing Dino Valenti's Get Together, years before the Youngbloods and Jefferson Airplane made it a peace-movement anthem. A newly unearthed take of Clark's You Movin' rocks beautifully. With help from producer Jim Dickson, the musicians explored jangly, harmony-drenched folk-rock in its early flowering, without pretense, commercial calculation or the psychedelic and country angles toward which they later veered.
