Damon Albarn used a "replica of Lou Reed's voice" on Gorillaz track The Plastic Guru.
The 57-year-old singer included contributions from a number of his late collaborators on the band's new album The Mountain - including Mark E. Smith and rapper Proof - but he's revealed issues with Reed's estate prevented him from using a recording of his voice on the new track so he had to come up with an alternative way to feature his late pal, who died in 2013.
