Rock legend David Bowie's death at the age of 69 has prompted an outpouring of tributes, but his influence reached beyond the impact of his music. He was also a financial innovator.

The bond issue earned Bowie $55 million, which he reportedly used to buy back songs from his catalog owned by his former manager. Read the original story from MarketWatch.
