Isolation is the Gold-certified fifth studio album by Toto, released on October 18, 1984. This was one of two albums the band made with Fergie Frederiksen as the primary vocalist, the other being their soundtrack to Dune. Isolation failed to achieve the popularity of its predecessor, Toto IV, although it achieved gold record status and gave the band their highest charting mainstream rock single "Stranger in Town" (No. 7). Relatively few songs from this album were featured in live performances after 1985's Isolation World Tour.
