In a Glass House is an album by British progressive rock band Gentle Giant, released in 1973.One of Gentle Giant's most popular albums (although the band themselves were not happy with it at the time, being made under pressure of Phil Shulman's departure), it was available in North America only as a rare import – both LP and CD – until 2004 when a digitally remastered CD was released. This was because their US label Columbia Records rejected the album as uncommercial.
