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.
On Who's Next, the song had to stand alone as a meditation of one man's dual nature, and the result was one of the most powerful and mature performances on the album. However, Behind Blue Eyes showed that the band had learned how to generate tension and drama through other means.
