A Valid Path is the fourth solo album by English rock musician Alan Parsons. The record was released on 24 August 2004 via Artemis label. Background The gap between this and his previous album, The Time Machine, was the third greatest period between two consecutive albums, after the time between the split of The Alan Parsons Project and Parsons' first solo work (not counting Freudiana) and the time between this album and The Secret. In addition to contributors such as David Gilmour, another noteworthy musical credit on the album is Parsons' son, Jeremy Parsons, his debut appearance on his father's albums. A Valid Path was released on Audio CD and DualDisc, with the DualDisc containing the album recorded in 5.1 Surround in both DTS and Dolby Digital formats. Other features of the DualDisc include a track commentary by the artist and interviews with Alan Parsons and the main collaborators on the release including David Gilmour and The Crystal Method.
