"Life in a Glasshouse" is a song written by the English alternative rock band Radiohead that appears on their 2001 album Amnesiac. It is performed by lead singer Thom Yorke with the late British trad jazz trumpeter Humphrey Lyttelton and his band. Beginning with a brief atmospheric loop and clanging church-like bells, the song quickly morphs into a funereal new orleans jazz style number by a horn section including a clarinet, a trumpet and a trombone. The song is also available with a slightly extended introduction as a b-side to the Knives Out single.
