"Welcome to the Machine" is the second song on Pink Floyd's 1975 album Wish You Were Here. It features heavily processed vocals, layers of synthesizers, acoustic guitars as well as a wide range of tape effects. Both the music and lyrics were written by bassist Roger Waters.

The In the Flesh Tour, also known as the Animals Tour, was a concert tour by the English rock band Pink Floyd in support of their 1977 album Animals. It was divided in two legs: one in Europe and another in North America. The tour featured large inflatable puppets, as well as a pyrotechnic "waterfall", and one of the biggest and most elaborate stages to date, including umbrella-like canopies that would rise from the stage to protect the band from the elements.
