In title and concept, the new tribute album Dionne Dionne is a great gimmick. But if you've followed the career of Dionne Farris, having her record an entire album of Dionne Warwick covers isn't an obvious move, names aside. It's an idea that took root some 20 years ago: Farris met guitarist Charlie Hunter while the two were on tour as members of hip-hop groups, she with Arrested Development and he with The Disposable Heroes of Hiphoprisy.

Marcos Garcia took his alter ego Chico Mann not from the 1970s TV series Chico and the Man but from a bit of dialogue in the early-'80s hip-hop film Wild Style. For years, Garcia was best-known as one of the members of the New York Afrobeat ensemble Antibalas. But one day, he began tinkering with his daughter's Casio keyboard, and since then he's only built on his arsenal of electronic playthings.

This isn't the first time Shuggie Otis' masterpiece, Inspiration Information, has been reissued — but that's OK. It's an album that absolutely deserves to be rediscovered every decade or so.

The very first notes on Laura Mvula's new album feel like a powerful invocation. You're not sure for what, but the moment is awesome — with an emphasis on awe.

It's tempting to describe the voices of Charles Bradley and

R&B singers Nicole Wray and Terri Walker both had promising starts to their careers more than ten years ago. Wray came up on the Virginia coast under the wing of mentor Missy Elliott. Walker, a Londoner, was classically trained yet released her debut on a Def Jam subsidiary. Both enjoyed early critical success but by decade's end struggled to find a wide audience. Instead, they found each other.

Bill Withers' very first single became a breakout hit in 1971. He would go on to record nine albums over the next 14 years, and all of them are now available on a new box set, The Complete Sussex and Columbia Masters.

Early synthesizers were supposed to imitate or re-create other existing sounds, but as anyone can tell you, they mostly sounded like synthesizers. That distinctive whine and wheeze captivated all manner of pop artists, from prog-rockers to classical composers to soul musicians. However, back then, synthesizers were so expensive and bulky, you needed a major-label budget and an entire studio wall to install them.

Few 20th century thinkers predicted the 21st century era of social media and the Internet better than Marshall McLuhan. Beginning in the 1960s, the Toronto-based philosopher and scholar began to theorize about how television and radio were changing society, creating what he termed the "global village."

Before the rise of Def Jam as hip-hop's definitive record label, there was Profile, which helped shepherd in some of the genre's early shifts in sound and style. A new two-CD anthology, Giant Single: The Profile Records Rap Anthology, chronicles the label's 15-year history and legacy.

My favorite part of Watch the Throne, the new joint release by Kanye West and Jay-Z, was waiting for it to come out. With no leaks and no advances, we were all reduced to waiting together, resurrecting the memory of rushing record-store doors the day of release.
