The ninth volume of 's ongoing girl group chronicle relies on a few new-to-CD singles, along with three unreleased recordings from the vaults. This is collector bait but, by this point, the hallmark of the series is that it doesn't concentrate on the familiar; it excavates the interesting tunes beloved -- or perhaps desired -- by collectors. As such, there isn't much surprise in sound or format here but that's fine: anybody dialing into this collection will want to hear arrangements, florid harmonies, and heartbreak, which is precisely what this compilation delivers. A few cuts dazzle -- the melodrama of ' "What a Lonely Way to Start the Summertime," the swinging style of ' "Billy Sunshine," the rhythms of ' "I Can Tell (I'm Losing Your Love)" -- but the appeal of is the consistency, how it delivers the sound you love without ever serving up a dull moment...something that's pretty impressive nine volumes into a series. ~ Stephen Thomas Erlewine
