Sound + Vision is David Bowie's box set compilation released on Rykodisc in 1989. By the end of the 1980s, the rights to Bowie's pre-1983 catalogue (released under the RCA label) reverted to Bowie. Rykodisc had approached Bowie in 1988 to re-release albums on CD and Bowie agreed, and in September 1989 the Sound + Vision box set was released. By April 1990 the box set had sold over 200,000 copies, which, for a set costing $50–$60 (or about $100 today) was considered "phenomenal."
