Q:What concert tour did critics say was overproduced?  Answer the above question based on the context below:  Tonight (1984), another dance-oriented album, found Bowie collaborating with Tina Turner and, once again, Iggy Pop. It included a number of cover songs, among them the 1966 Beach Boys hit "God Only Knows". The album bore the transatlantic Top 10 hit "Blue Jean", itself the inspiration for a short film that won Bowie a Grammy Award for Best Short Form Music Video, Jazzin' for Blue Jean. Bowie performed at Wembley Stadium in 1985 for Live Aid, a multi-venue benefit concert for Ethiopian famine relief. During the event, the video for a fundraising single was premiered, Bowie's duet with Mick Jagger. "Dancing in the Street" quickly went to number one on release. The same year, Bowie worked with the Pat Metheny Group to record "This Is Not America" for the soundtrack of The Falcon and the Snowman. Released as a single, the song became a Top 40 hit in the UK and US.Bowie was given a role in the 1986 film Absolute Beginners. It was poorly received by critics, but Bowie's theme song, also named "Absolute Beginners", rose to No. 2 in the UK charts. He also appeared as Jareth, the Goblin King, in the 1986 Jim Henson film Labyrinth, for which he wrote five songs. His final solo album of the decade was 1987's Never Let Me Down, where he ditched the light sound of his previous two albums, instead offering harder rock with an industrial/techno dance edge. Peaking at No. 6 in the UK, the album yielded the hits "Day-In, Day-Out" (his 60th single), "Time Will Crawl", and "Never Let Me Down". Bowie later described it as his "nadir", calling it "an awful album". Supporting Never Let Me Down, and preceded by nine promotional press shows, the 86-concert Glass Spider Tour commenced on 30 May. Bowie's backing band included Peter Frampton on lead guitar. Contemporary critics maligned the tour as overproduced, saying it pandered to the current stadium rock trends in its special effects and dancing, although years after the tour's conclusion, critics acknowledged that the tour influenced how other artists performed concerts, including...
