Reuniting Bowie with Eno, the quasi-industrial "Outside" (1995) was originally conceived as the first volume in a non-linear narrative of art and murder. Featuring characters from a short story written by Bowie, the album achieved UK and US chart success, and yielded three Top 40 UK singles. In a move that provoked mixed reaction from both fans and critics, Bowie chose Nine Inch Nails as his tour partner for the Outside Tour. Visiting cities in Europe and North America between September 1995 and February 1996, the tour saw the return of Gabrels as Bowie's guitarist. On 7 January 1997, Bowie celebrated his half century with a 50th birthday concert at Madison Square Garden, New York, at which he was joined in playing his songs and those of his guests, Lou Reed, Dave Grohl and the Foo Fighters, Robert Smith of the Cure, Billy Corgan of the Smashing Pumpkins, Black Francis of the Pixies, and Sonic Youth.
