It's this latter category that John Legend and The Roots focus on in Wake Up! - covers of mostly little-remembered tracks. The songs' messages swing between the barely contained anger of Hard Times and the funktastic Compared to What, the call to action of Wake Up Everybody and the hopefulness of Hang On In There.
Legend's velvety voice may not seem suited to revolution songs but, combined with the intricate arrangements provided by The Roots and guest artists' up-to-date rapping, each song is respectfully given a modern makeover. It keeps the original message and vibe intact, yet updates the sound for a contemporary audience.
Some people may argue that recreating songs born of a revolutionary period shows a lack of understanding for the struggles of the time. But these songs still speak to us; inequality still exists. Besides, good music is good music, irrelevant of what's going on. And this is amazingly good music.
