 His production and songwriting credits include Lykke Li, Chrissie Hynde, Primal Scream, Franz Ferdinand, Sahara Hotnights, Anna Ternheim.

 He is also a co-founder of the label and artist collective INGRID and a member of the band LIV.
Last of the Independents is the sixth album by rock group The Pretenders, released in 1994.
 For this album, the band is officially credited as being Chrissie Hynde (vocals, guitar), Adam Seymour (guitar), Andy Hobson (bass) and Martin Chambers (drums).
 However, this line-up only plays together on one track ("All My Dreams"); the rest of the album is performed by Hynde and Seymour in conjunction with a rotating series of musicians on bass and drums.
 These musicians include Hobson and Chambers, as well as bassists Andy Rourke, Tom Kelly and David Paton, and drummers Jimmy Copley and J.F.T. Hood.
 A few other session musicians also appear, including Ian Stanley, and one-time Pretenders guitarist Robbie McIntosh, who plays alongside Hynde and Seymour on "I'm a Mother".
Reckless: My Life as a Pretender is a memoir by the American musician Chrissie Hynde, a member of rock band The Pretenders.
 The book was published on September 8, 2015 by Doubleday, New York and London.
 In it, Hynde documents her childhood and youth in the Midwest, the founding of The Pretenders, life on the road and interactions with other musicians.
The Pretenders are an English-American rock band formed in Hereford, England, in March 1978.
 The original band consisted of initiator and main songwriter Chrissie Hynde (lead vocals, rhythm guitar), James Honeyman-Scott (lead guitar, backing vocals, keyboards), Pete Farndon (bass guitar, backing vocals), and Martin Chambers (drums, backing vocals, percussion).
 Following the drug-related deaths of Honeyman-Scott and Farndon, the band has experienced numerous subsequent personnel changes, with Hynde as the only consistent member, and Chambers returning after an absence of several years.
Christine Ellen "Chrissie" Hynde (born September 7, 1951) is an American musician who is best known as a founding member of the rock band The Pretenders.
The singles discography of Eric Clapton consists of 24 early career singles that Clapton recorded with various bands and artists including The Yardbirds, John Mayall & the Blues Breakers, Cream, John Lennon and the Plastic Ono Band as well as Derek and the Dominos.
 As a solo artist, Clapton released 91 singles and various promotional formats from 1970 to date.
 His commercially most successful singles are "Lay Down Sally", "Wonderful Tonight", "Change the World", "Tears in Heaven" and the cover of Bob Marley's "I Shot the Sheriff", released in 1974, that actually outplayed the original release, becoming a "Billboard" Hot 100 number-one hit.
 Clapton's best-selling single is "Wonderful Tonight" which has sold more than four million copies worldwide, although he is most known for his rock anthem "Layla", that was originally released in 1971.
 Clapton later covered the song acoustically for his 1992 "Unplugged" million-seller, and helped to cement Clapton's reputation as both a guitarist and singer.
 The British rock musician also collaborated with friends along his extensive solo career.
 Featured singles with artists like Elton John, Sting, Cher, Chrissie Hynde, Neneh Cherry and Zucchero Fornaciari helped to uplift Clapton's single performances.
Packed!
 is the fifth album by rock group The Pretenders, released in 1990.
 For this album, the only real member of the group is Chrissie Hynde; no other person is pictured anywhere within the album package, and a rotating cast of session musicians (rather than a set band) is used to back Hynde throughout, essentially making this a de facto solo album by Hynde, only using the Pretenders name to satisfy contractual obligations.
 However, drummer Blair Cunningham plays on all tracks, though he is not credited as part of the band.

Martin Dale Chambers (born 4 September 1951 in Hereford) is an English musician, who is best known as a founding member and drummer of the rock band the Pretenders.

 He was part of the original band line-up which also included Chrissie Hynde (vocals/guitar), James Honeyman-Scott (guitar/vocals/keyboards) and Pete Farndon (bass guitar/vocals).
 Hynde and Chambers are the only two surviving original members, and he has served two separate tenures with the group.
