Delta blues giant Robert Johnson (May 8, 1911–August 16, 1938) is one of the most fascinating and mysterious performers in music history. He created an essential body of blues guitar music, recording 29 songs in 1936 and 1937 that would exert a powerful influence on the likes of Eric Clapton, Jimi Hendrix, Keith Richards, Johnny Winter and many others. In this edition of In Deep, we’ll examine the variety of picking techniques and tunings that Johnson used to craft his timeless, deeply emotional music.

Originally intended to mimic the sound of a muted trumpet, it didn't take long for guitarists like Jimi Hendrix and Frank Zappa to make that sweet, sweeping "wah-wah" sound an integral part of the rock and roll lexicon.

David Bowie has released a new music video for "The Next Day," the title track from his latest album.

Critics snubbed it upon its release in 1972, but Exile on Main St. has become one of rock’s greatest landmarks. Keith Richards recalls the making of the Rolling Stones' masterpiece and how the album’s new reissue project became a walk down memory lane.
