Isolation is the fifth studio album by American rock band Toto, released in October 1984. It is the first album to include Mike Porcaro as the band's official bassist and the only album with Fergie Frederiksen as the primary vocalist. While Isolation failed to achieve the popularity of its predecessor, Toto IV, it achieved gold record status and gave the band their highest charting mainstream rock single "Stranger in Town". Relatively few songs from this album were featured in live performances after 1985's Isolation World Tour due to Frederiksen's departure and the lack of well-known material from the album.
