"Wire & Glass" is the first single released from The Who's 2006 album, Endless Wire. The single was released exclusively to the iTunes Music Store on 17 July 2006 and a Maxi-CD/12" was released a week later (see 2006 in British music). The single was released as a "mini-opera" in six songs. No North American distribution was secured prior to the release of the full album, Endless Wire. As of August 3, 2006, it is the best selling Who album on iTunes in the UK.
The single reached the top three on the Canadian Singles Chart. The songs from this album were used in the rock musical adaptation of The Boy Who Heard Music which debuted in July 2007 as part of Vassar College's Powerhouse Summer Theater workshop series.
