Alan Charles Wilder (born 1 June 1959) is an English musician, composer, arranger, record producer and member of the electronic band Depeche Mode from 1982 to 1995.

Following the departure of Vince Clarke, Depeche Mode placed an advertisement in the music magazine Melody Maker: "Keyboard player needed for established band – no timewasters."

He joined Depeche Mode in January 1982, initially as a tour keyboardist and soon thereafter as a full member of the recording band.

For "Enjoy the Silence" from the album Violator, Wilder took Martin Gore's melancholy ballad-esque demo and re-envisioned the song as a percolating, melodic dance track.

In June 1995, Wilder announced his departure from Depeche Mode "due to increasing dissatisfaction with the internal relations and working practices of the group".

[7] Wilder briefly reunited with Depeche Mode during the Teenage Cancer Trust concert at the Royal Albert Hall in London on 17 February 2010.

Simply entitled 1 + 2, the collection of primitive demos caught the attention of Mute Records label boss Daniel Miller and was inconspicuously released as a mini-album on 12" vinyl.

Bloodline also yielded the first two Recoil singles, a cover of Alex Harvey's song "Faith Healer" as well as "Electro Blues for Bukka White".

In August 1991, after marrying his first wife, Jeri Young, Wilder bought a 30-acre, eight-bedroom country estate in Itchingfield, West Sussex, England, where he later built his personal recording studio, The Thin Line.
