Phil Manzanera (born Philip Geoffrey Targett-Adams, 31 January 1951) is a British musician and record producer. He was the lead guitarist with Roxy Music, 801, and Quiet Sun. As a writer, producer and solo artist, Phil Manzanera has worked with many of the luminaries of modern music, such as Steve Winwood, David Gilmour, John Cale, Godley & Creme, Nico and John Wetton.

Manzanera's first solo album 'Diamond Head' (1975) featured an all-star line-up of session contributors, including most of the former and current members of Roxy Music, except Bryan Ferry. Concurrent with the recording of 'Diamond Head', Manzanera reunited his pre-Roxy group, Quiet Sun  and used the studio time to quickly record a full LP of Quiet Sun material, released by EG Records under the title Mainstream.

Reworked versions of two tracks from 'Mainstream' featured on Manzanera's next major collaboration, the critically acclaimed concert recording '801 Live'. A new line-up of 801 recorded the studio album 'Listen Now', which was released in November 1976.

Manzanera's second solo album 'K-Scope' (1978) was originally intended to be the second 801 studio album, and indeed it featured many of the same personnel from 'Listen Now', including Ainley, Bill and Ian McCormick, John Wetton, Simon Phillips, Mel Collins, Tim and Neil Finn, Eddie Rayner, Godley and Creme and keyboard player Dave Skinner. His third solo album 'Primitive Guitars' followed in 1982.

In 2011 the riff from 'K-Scope' was used in opening track of the Jay-Z and Kanye West album 'Watch the Throne'.  The sample that ended up forming a crucial component of the duo’s song 'No Church in the Wild' is a slowed-down clip from the title track to his 1978 solo LP 'K-Scope'. As Manzanera soon discovered, the sample was brought to Jay-Z and West by a producer named 88-Keys, who found a copy of 'K-Scope' during a bout of crate-digging and ended up giving Manzanera an unexpected late-career highlight: not only did 'Watch the Throne' go platinum, but 'No Church in the Wild' started popping up all over the place — in soundtracks, commercials and even in an episode of the BBC series Silent Witness that he happened to watch while vacationing in Burma.
