Singer/songwriter Joni Mitchell toured her past, journeyed into a new genre and trekked across the ocean for A Travelogue, her long-awaited collaboration with the London Symphony Orchestra. The two-CD set, due Nov. 19 on Reprise, offers 23 of her compositions, freshly arranged by Vince Mendoza.

Mitchell, who produced the retrospective with ex-hubby and longtime collaborator Larry Klein, recorded the songs at George Martin's Air Lyndhurst Studio in London.

Tunes transformed from pop simplicity to classical grandeur include Woodstock, Amelia, Chinese Café, Flat Tire, For the Roses, God Must Be a Boogie Man, Sex Kills, Be Cool, Just Like This Train, The Last Time I Saw Richard and Circle Game.

Mitchell designed the packaging, which features examples of her paintings, a book and extensive liner notes.

Making appearances are Herbie Hancock, Billy Preston and Wayne Shorter.

The recording sessions are chronicled in a documentary by Allison Anders (Mi Vida Loca, Gas Food Lodging), tentatively due in January. In addition, PBS will air an American Masters profile of Mitchell in March.
