When a great artist passes, among the outpouring of love you'll find a plethora of tributes from the musicians who derived inspiration from them. First a wave of covers of a few of the artist's most successful songs. When Bowie died there was a deluge of 'Heroes' covers in the following weeks, as if the man with a legendary career spanning six different decades had only struck gold with the one tune. Then the covers of oddities and deep cuts come out and we get to re-experience the career of the artist through new ears. The true legacy comes from the endless ripples of inspiration that permeate from the musician's catalogue out into the culture and affect songwriters for decades to come. In some ways that is the truest form of tribute.
