Please answer the following question: Given the following context:  Lukather is the original lead guitarist for Toto, serving in that capacity for the band's entire history, as well as a lead and backing vocalist and composer. Lukather won three of his five Grammy Awards for work with Toto, twice as an artist and once as a producer. David Paich led the band's songwriting efforts during the development of 1978's Toto—he penned all but two of the album's tracks, including all four of its singles. Lukather also credits Jeff Porcaro for his leadership within the band during that period. However, Lukather's role in Toto evolved over time owing to the changing needs of the band. In August 1992, Jeff Porcaro collapsed while doing yard work at home and subsequently died of heart failure. The death profoundly affected Toto and Lukather in particular, who felt that he needed to step up and make sure the band kept going. Thus, he began taking more of a leadership role. Toto went through several lead vocalists over the years, including Bobby Kimball, Fergie Frederiksen, and Joseph Williams. After the 1990 dismissal of their fourth vocalist, Jean-Michel Byron, Toto was without a lead singer until around 1997; Lukather assumed most of the vocal duties for the band during that time. He performed lead vocals for every track on 1992's Kingdom of Desire and 1995's Tambu except for two instrumental tracks. The Tambu single "I Will Remember", co-written by Lukather and Stan Lynch, reached number 64 on UK charts. Some Tambu reviewers contrasted Lukather's vocals with those of former singers Kimball and Williams (and indeed, heavily criticized the entire album), some concert reviewers noted that he struggled vocally on certain songs, and a number of backup singers and guest vocalists accompanied the band's live shows during that period. It was not until Toto brought back Williams and Kimball to collaborate on 1998's Toto XX that Lukather returned predominantly to the role of backup vocalist.Lukather's songwriting contributions grew from a smattering of tracks on early Toto albums to co-writing...  answer the following question:  What albums did the original lead guitarist for the band that had a member die in August 1992 perform lead vocals on?
Answer:
Tambu
