John spent his early musical career in Automatic Dlamini releasing two albums and a handful of singles through various independent labels. In 1986 he "accidentally" became a producer after helping neighbors The Chesterfields record their debut EP, which became a UK chart hit. The calls started coming- most notably from former Automatic Dlamini bandmate PJ Harvey. This relationship would turn out to be his most fruitful, placing John squarely on the map as a producer and musician. Together with PJ Harvey, John served as a co-producer and featured musician (guitar, bass, keys and percussion) for her landmark album To Bring You My Love (Island 1995). He was again a featured musician on the follow up Is This Desire? (Island 1998) and was a mainstay of the PJ Harvey touring band between the years of ’95 to ’99. In 1996 he wrote the music and played all the instruments for Dance Hall at Louse Point (Island) a collaboration between the two which was credited under both their names. As a producer and contributor, John has been involved in some of the most critically acclaimed albums of the past few years including Sparklehorse's It's A Wonderful Life, Goldfrapp's Felt Mountain and Giant Sand’s Chore Of Enchantment. In 2001 John again donned the hat of writer, producer and musician for the Eels and their landmark album Souljacker (Dreamworks),which was named as album of the year by Time magazine. He later went on to play guitar with the Eels during their world tour from July – December of that same year. More recently John has been found working with Tracy Chapman and M Ward amongst others.
