Sound of Silver is the second album from LCD Soundsystem. The album was released in the UK on March 12, 2007 and in the U.S. on March 20, 2007.

Songs in the Sound of Silver, notably "Someone Great," feature parts of the 2006 LCD Soundsystem release 45:33.

For several weeks before and after the album's release the entire album was available for streaming on the band's MySpace page. The video for the track "North American Scum" was also posted to the band's MySpace on February 8, 2007.

On March 12, 2007, to coincide with its official UK release, an underground remix version of the album was released on the internet in aid of charity.

The album reached number 28 in the UK charts. James Murphy has stated that he would like the album to be in the Top 40 on the U.S. Billboard Charts. It debuted on the Billboard 200 at number 46.

The album is dedicated to "the memory of Dr. George Kamen (1942-2006), one of the great minds of his or any generation." The Bulgarian-born doctor was a pioneer of group therapy and had opened a practice in New York.

Carl Craig is a Detroit-based producer of techno music, and is considered to be one of the most important names in the Detroit second generation of techno producers and DJs. According to an article about Craig, "Of this group, Craig was often recognised as being the most artful and the most willing to engage the rapidly growing shape of techno outside Detroit." Carl Craig has approached techno using inspiration from a wide range of musical genres, including jazz and soul.

Carl Craig has released many successful albums under a large number of aliases, such as BFC, Psyche, Paperclip People, 69, Designer Music and Innerzone Orchestra. He also had a hugely successful collaboration album with NYDJ Patrick Picasso. Using one alias, Innerzone Orchestra, he released perhaps his best-known track "Bug in The Bassbin" in 1992, a track that many regard as being a key influence in the then evolving sound of drum and bass.

Carl Craig has also created his own record label called Planet E Communications, which apart from his own work, has released records by well known techno and house artists like Kevin Saunderson, Alton Miller and Moodymann.
