In Islamic beliefs, there exists iconoclasm, which is the opposition to religious use of images. They believe only God can create living things, so part of this movement was the destruction of art (such as rubbing out faces). There is no figural imagery on the Taj Mahal. Instead there are intricate designs of flowers, writings, patterns and carvings.
Behind Blue Eyes by The Who Songfacts. Pete Townshend originally wrote this about a character in his Lifehouse project, which was going to be a film similar to The Who's Tommy and Quadrophenia. Townshend never finished Lifehouse, but the songs ended up on the album Who's Next.
The version of Behind Blue Eyes on the original Who's Next album was the second version the band recorded; the first was recorded at the Record Plant in New York on 18 March 1971 and features Al Kooper on Hammond organ. The first version was released as a bonus track on the 1995 CD reissue of Who's Next.
