Question: Who were the sixteen musicians that appeared on The Colour of Spring? Passage:In 1986, Talk Talk, then a three-piece band consisting of leader and singer Mark Hollis alongside drummer Lee Harris and bassist Paul Webb, released their third album The Colour of Spring, which saw the band shift from their earlier, synthpop-oriented sound and featured a more organic art rock sound, where musicians improvised with their instruments for many hours, then Hollis and producer Tim Friese-Greene edited and arranged the performances to get the sound they wanted. A total of sixteen musicians appeared on the album. It became their most successful album, selling over two million copies and prompting a major world tour. Nonetheless, for their next album Spirit of Eden (1988), the band chose to work towards an even more unconventional and uncommercial direction. The album was compiled from a lengthy recording process at London's Wessex Studios between 1987 and 1988 where the band worked again with Friese-Greene and engineer Phill Brown. Often working in darkness, the band recorded many hours of improvised performances which were heavily edited and re-arranged into the final album.
