Although Lulu's mid-'60s Decca recordings have been issued piecemeal on numerous anthologies, somehow no one executed the logical idea of putting them all together on one release until this 42-track, two-CD collection. All of her 1964-1967 sides for the label are included, serving as a comprehensive document to the first three years or so of her recording career. Particularly in the U.S. (where she really wasn't known until the 1967 chart-topper "To Sir with Love," not included here), this period has remained rather obscure, and certainly not as familiar to the general rock fan as her more commercially successful recordings of the late '60s. This is a shame, as this was undoubtedly the era -- in spite of her tender teenage years -- in which she laid down her most soulful, R&B-influenced, and raunchiest recordings by far. With comprehensive liner notes, this is a necessary acquisition for Lulu fans, and a pretty good one for more general British Invasion admirers.
