7 cd set.  The Last Time Around brings to a close BEAR FAMILY's definitive 3-box overview of Rick Nelson's recording career. Still with his pioneering country-rock Stone Canyon Band, this set begins with four albums - Rick Sings Nelson, Rudy The Fifth, Garden Party and Windfall. Garden Party, of course, featured his last major hit in which he announced his refusal to become an oldies act. The set continues with the Intakes album recorded for EPIC, and Playing To Win, originally released on CAPITOL. And there's more!  For the first time in their entirety, BEAR FAMILY presents two previously unreleased albums: Back To Vienna produced in Hollywood by Al Kooper with a band of all-star session players; and The Memphis Sessions, with a sympathetic band of (mostly) locals, produced by Larry Rogers. And still more surprises include an entire, live performance recorded with the second-edition Stone Canyon Band heard here for the first time, as well as several single-only, previously unreleased studio sessions, and even a few commercials.    The 144-page album-sized hardcover book includes dozens of pictures and other artwork; a full sessionography; and a 25,000-word history by Todd Everett, author of the acclaimed notes for the earlier volumes in this series, An American Dream and For You. With the compelling first-person accounts, you'll hear the real stories behind the sessions.    Though Rick's later recordings assembled here didn't match the commercial impact of his earlier songs, they certainly maintained the quality. Rick went out rocking!
