Isolation is the Gold-certified 5th studio album by Toto, released on October 18, 1984. This was the only album the band made with Fergie Frederiksen as the primary vocalist, as he was let go following the album's world tour due to ongoing vocal problems. 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.
