Not quite the return to the "rock" side of Radiohead as originally believed (although pretty close), the band's sixth album (produced again by Nigel Godrich) retains some of the experimental electronica elements of its predecessors Kid A and Amnesiac. Note that each of the tracks on the album has an alternate title, as does the album itself (aka 'The Gloaming').

Like all of the band’s best work, Thief requires more than a few listens to fully appreciate, but those who stick around will be richly rewarded.Amazon

Hail to the Thief , or "The Gloaming" as it is subtitled, is the sixth studio album by Englishrock band Radiohead, released on June 9, 2003 in the United Kingdom and June 10 in the United States and Canada. After two albums that mined a distinctive groove, with heavily processed vocals and few guitars, Hail to the Thief draws its ideas from every era of the band's existence, coupled with a new-found confidence and live energy — the bulk of the record was recorded in two weeks in Los Angeles.

The album is dedicated to "Patrick and Tamir and a future worth having." Patrick and Tamir are sons of Phil Selway and Jonny Greenwood, respectively, born since the release of Amnesiac.
