The Visitor is the nineteenth studio album by the British hard rock band UFO, which was released on 2 June 2009. Bass parts were recorded by Peter Pichl. Since there are no writing credits on the album booklet, they were posted on UFO's official website (June 2009).
The digipak edition bonus track, "Dancing with St. Peter", had previously been recorded by Phil Mogg with his side project, $ign Of 4, featuring Mogg/Way guitarist Jeff Kollman, one-time Michael Schenker Group drummer Shane Gaalaas, and bassist Jimmy Curtain. The album was originally released in 2002 through Track Records and re-issued in 2008 by Kollman's label Marmaduke Records under the name Mogg & The Sign Of 4.
