Endless Wire is the eleventh studio album by the English rock band the Who, released on 30 October 2006 in the UK through Polydor Records and the following day in the US by Universal Republic.

It was their first new studio album of original material in 24 years following the release of It's Hard in 1982, as well as their first since the death of their founding bassist John Entwistle.

[20] On 28 March 2006, Townshend announced through the diary portion of his website that a mini-opera, titled "The Glass Household", now formed the core of the album.

On 9 April 2006, Townshend announced that the shortened version of "The Glass Household" had been played to executives at Polydor, and a release date had been set for June, with a tour of Europe following, and the album in September.

[22] On 3 May 2006, Pete Townshend posted on his diary page that the mastering for the new EP, titled Wire & Glass, was complete and that the tracks would soon be sent to Polydor.

Then on 14 October 2006, Polydor built a website for the album, endlesswire.co.uk, on which samples of the songs "We Got a Hit", "Endless Wire", "It's Not Enough", "Black Widow's Eyes", "Mike Post Theme", and "Man in a Purple Dress" were made available to listen to, but not to download.

It was recorded in the studio with Zak Starkey on drums, and Daltrey on vocals, but Townshend expressed doubt on whether it would make it on the album or not when he first played it on in the Attic, and it was not included.

On 18 December 2005, Pete Townshend posted a diary entry that chronicled the recording of this track: Here is a film I made of a working day developing a demo of a song for the next Who album called "How Can I Help You, Sir?"

Townshend is also working the songs from this album into a full-length rock musical, a rough version of which debuted 13 July 2007 as part of Vassar College's Powerhouse Summer Theater workshop series.

The cast included John Hickok as Ray High, Jon Patrick Walker as Josh, Matt McGrath as Gabriel, and Bree Sharp as Leila.

"It's Not Enough" reached number 37 on the US Billboard Mainstream Rock Tracks chart, where it was released as a B-side with "Black Widow's Eyes".
