The greatest contribution David Bowie made was by being himself - his open minded approach to change facilitated through his use of different personas, musicality and fashion gave him the edge.
He somehow managed to be both outsider and populist by making sure his songwriting was always on the move and a true reflection of his latest persona. He followed the erratic path of the resolute artist, a groundbreaker, a giant, trying new stuff, re-inventing himself repeatedly.
His range of music is astonishing, from hard rock and dance to experimental electronica, from soft ballad to funked up soul and on into jazz.
His singing voice was distinctive, his use of guitars and sax innovative, his willingess to work with other artists (including the crooner Bing Crosby!) to explore new areas kept his creations fresh.
His latest album tests the boundaries again. He knew the end was coming and transformed what could have been a sad, tearful send off into one of drama, mystery and art. Some accomplishment.
