"[9] Part of the reluctance to tour was the ongoing personal and legal drug-related problems of lead vocalist Bobby Kimball.

"[9] Even that reportedly required weeks of work, primarily because of Kimball's tendency to not show up for sessions and, when he did, to struggle with the vocals which were at the top of his range.

The commercial failure of Dune served only to add insult to the injury of having lost their lead vocalist.

[9] Lukather then wanted to offer the job to Eric Martin, later of Mr. Big, but Porcaro was interested in Fergie Frederiksen, then lead singer of the band LeRoux.

Although Frederiksen would begin work with Toto on their sixth album, Fahrenheit, he struggled with the vocals for the first track, "Could This Be Love," and the band moved on to Joseph Williams.

AllMusic's retrospective review praised the performances of Jeff Porcaro, David Paich, and Steve Lukather in passing but dismissed Isolation as "a Journey clone album, minus the aching ballads that had made Journey such a success.
