Before setting rock "n" roll on its ear in the spring of "65, the Byrds spent long hours perfecting their unique sound at L.A"s legendary World Pacific Studios, and it is this treasure trove of material-only partially documented previously by the Preflyte album-that comprises this 40, yup, 40-track set! Among the 16 unreleased cuts: versions of I Knew I"d Want You; She Has a Way; It"s No Use; For Me Again; The Reason Why; You Showed Me , and The Times They Are A-Changin" along with unreleased David Crosby demos and the rare, pre-Byrds Jet Set recording of The Only Girl I Adore . A 52-page booklet takes you back to the very beginning of perhaps the greatest American rock band.
