Answer by taking a quote from the following article:

Triumph is a Canadian hard rock band formed in 1975 that was popular in the late 1970s and the 1980s, building on its reputation and success as a live band. Between the band's 16 albums and DVDs, Triumph has received 18 gold and 9 platinum awards in Canada and the United States. Triumph was nominated for multiple Juno Awards, including Group of the Year Award in 1979, 1985, 1986, and 1987. Triumph is most known for its guitar-driven rock songs, such as "Lay It on the Line", "Magic Power", "Fight the Good Fight", and "World of Fantasy".

Triumph would take a more commercial turn with their 1986 studio album, The Sport of Kings. Rik Emmett's "Somebody's Out There" reached the American Top 40 in late 1986, a significant amount of radio and video exposure. Written and recorded in the 11th hour of The Sport of Kings sessions, in an attempt to deliver a hit 'single' to satisfy the demands of the record company, "Somebody's Out There" made it to No. 27 on Billboard Hot 100 during October and November 1986. "Somebody's Out There" still stands as the highest-charting song from the Triumph catalogue on the Hot 100. It also reached No. 9 on the Top Rock Tracks chart, although it did less well in Canada, only reaching No. 84 on the Singles chart there. Gil Moore's "Tears in the Rain", cut from the same cloth as "Mind Games", did not fare as well in the charts in the US, as it peaked at No. 23 on the Top Rock Tracks charts. The third single, the slow-tempo "Just One Night", which also had a video, did fairly well in Canada hitting No. 33 on the Singles chart in April 1987, but did not chart in the US. Adding Rick Santers to their line-up, Triumph toured with Swedish guitarist Yngwie Malmsteen across the United States.  In 1987, the band attempted a return to form with Surveillance. While Gil Moore and Mike Levine remained firmly planted in blues-rock, Rik Emmett took a more modern progressive turn, even involving Dixie Dregs and Kansas guitarist Steve Morse. They collaborated on a dual-guitar solo for Gil Moore's angst-ridden vocal on the Emmett-penned "Headed for Nowhere". The first single released to radio stations in Canada was "Let the Light Shine On Me", which did well on certain Canadian rock stations, such as reaching number 1 at Q107 in Toronto (as the lead one or two singles on most Triumph albums since 1979 had) while reaching No. 61 on the Canadian singles chart. It did not chart in the US. The first single released to radio stations in the US, "Long Time Gone," reached number 23 on the Top Rock Tracks chart; the song did not chart in Canada. A video was released for the single "Never Say Never," but the song was not able to chart on the Top Rock Tracks chart or on the Canadian Singles chart.  The 1988 tour concluded amid growing disharmony over business decisions and artistic direction; however, their final concert on September 3, 1988, was a spirited show on the Kingswood stage at Canada's Wonderland, just north of Toronto. In late 1988, Rik Emmett made a total break with Triumph. He subsequently began a modest but distinguished solo career, with his first album, Absolutely, yielding four hits in Canada. Meanwhile, Triumph released 1989's Classics as their obligatory fifth album owed to MCA Records.

How did the critics react to the album?
