The Glass Spider Tour was a 1987 worldwide concert tour by the English musician David Bowie, launched in support of his album Never Let Me Down and named for that album's track "Glass Spider". It began in May 1987 and was preceded by a two-week press tour that saw Bowie visit nine countries throughout Europe and North America to drum up public interest in the tour. The Glass Spider Tour was the first Bowie tour to visit Austria, Italy, Spain, Ireland and Wales. Through a sponsorship from Pepsi, the tour was intended to visit Russia and South America as well, but these plans were later cancelled. The tour was, at that point, the longest and most expensive tour Bowie had embarked upon in his career. At the time, the tour's elaborate set was called "the largest touring set ever".
