This 16-track compilation covers Senegalese singer/songwriter and multi-instrumentalist Youssou N'Dour's Columbia Records period, from 1991 to 1996. Perhaps the most popular pop culture figure in Senegal's history, N'Dour created a music of his own from various sources, which he called "mbalax" and which incorporates everything from jazz, soul, hard R&B styles, hip-hop, and even Cuban samba, and juxtaposes them with the folk melodies and polyrhythms of his native land. The cuts here, particularly "Old Man," "New Africa," "Yo le Le, (Fulani Rhythm)," and the covers of Smokey Robinson's "Don't Look Back," and Lennon and McCartney's "Ob-La-Di-Ob-La-Da," reveal N'Dour's idiosyncratic, yet very accessible grasp and integration of Western and African pop styles.

John Lennon would have turned 67 in 2007. If alive, he could well be at the forefront of bringing peace to Darfur, where more than half a million have died from violence and disease during four years of rebel discord. So to create awareness of the ongoing conflict, Amnesty International (with permission from Yoko Ono) has mined Lennon's solo work and rounded up nearly two dozen current artists to reinterpret the music, which spans the ex-Beatle's entire post-band catalog (plus a pair from while the Fab Four were still in business). As with any attempt to cover Beatles-related music, results are hit and miss, with kudos going to Snow Patrol and the Postal Service for capturing the starkness of "Isolation" and "Grow Old with Me," respectively, Mexican rock band Jaguares for uncovering the fear and fury in "Gimme Some Truth," and (surprise!) Christina Aguilera for nailing the complex composition and mood of "Mother." Other highlights include Jackson Browne's piano-led "Oh My Love," Green Day's louder straight take on "Working Class Hero," and the Black Eyed Peas turning "Power to the People" into a gospelly protest. Will resurrecting 30-to-40-year-old messages of peace and love be enough to help end the brutalities in Darfur? That remains to be seen. But selecting John Lennon as the author of those messages will make people listen and, with this collection, may keep them listening.

Taken from material released in the '80s by the French Melodie label, these pieces were recorded before N'Dour became a major international star (as the title indicates). As such, he was making music for the home market, which wanted its mbalax sound hard – and that's what he gave them. He was still putting the elements together, but the basic components were in place – the rhythm and that remarkable high griot voice, then at its raw best. It's interesting to compare "Alboury" in this version to the one on Set, several years later. There's a pumping energy here that has become channeled on the later recording – maybe not as focused, but with a flavor of youth that's undeniable. And that energy transmits itself through all these tracks.
