Deep Purple are a British rock band formed in Hertford in 1968. They are considered to be among the pioneers of heavy metal and modern hard rock, although their musical style has varied throughout their career.

The Book of Taliesyn is the second studio album by the English rock band Deep Purple, recorded only three months after Shades of Deep Purple and released by Tetragrammaton Records in December 1968, during their first US tour. The name for the album was taken from the 14th-century Book of Taliesin.
