Janis Joplin, The Pearl Sessions (Columbia/Legacy)
Essentially a new double-disc deluxe edition of Joplin's final album, with mono single mixes and a heap of mostly unreleased session outtakes as bonus tracks.
Little Richard, Here's Little Richard (Specialty/Concord)
One of the cornerstone albums of modern rock is newly remastered and expanded with two demos, video content and an interview with Specialty label founder Art Rupe.
Bob Marley & The Wailers, Marley: The Original Soundtrack (Tuff Gong/Island)
It won't supplant Legend, but this new two-disc compilation (to tie in with the new film) features hits, early obscurities and an unreleased live version of "Jammin'" from the historic One Love Peace concert.
Aretha Franklin, Who's Zoomin' Who? Deluxe Edition (Funky Town Grooves)
The Queen of Soul's legendary '80s comeback, expanded with every mix and edit of hit singles like "Freeway of Love," "Sisters Are Doin' It for Themselves" and the title track.
Cowboy Copas/Little Willie John/The Ad Libs, Complete Hit SIngles As & Bs (Real Gone Music)
The latest from Real Gone compiles singles from pioneers of their genres (country for Cowboy Copas, doo-wop for The Ad Libs and R&B for Willie John).
Grand Funk Railroad, Mark, Don & Mel 1969-71 (Iconoclassic)
This classic GFR compilation has been released by Iconoclassic before, but previous copies were plagued with mastering issues. Now, they've all been cleared, and if you buy now, you'll get a good one.
Luther Vandross, Hidden Gems (Epic/Legacy)
In honor of what would have been the late crooner's birthday, a new single-disc compilation highlighting lesser-known album tracks and soundtrack rarities.
Four double-disc Essential sets from Legacy, but only one (from recent Rock and Roll Hall of Fame inductee Donovan) isn't a repackaging of a prior compilation.
