After their smash hit "Big House" in 1992, Audio Adrenaline has remained a popular staple in Christian rock for 15 years, amassing 18 No. 1 hits, three million albums sold, four Gospel Music Awards, and a loyal fan following. But regular touring has not been kind to Mark Stuart's voice over the years, and with the gradual departure of key band members throughout the band's history, retirement makes perfect sense at this point.

The group will still remain active in missions and management through their Hands and Feet Project and their label Flicker Records, plus guitarist and co-lead vocalist Tyler Burkum is busy developing a solo career. But now comes the time to bid a fond farewell—or adios, as it were—to a beloved band and their enduring catalog of music. Adios: The Greatest Hits gives an overview of Audio A's entire career, featuring 12 of their No. 1's on a 17-track retrospective.

All well and good, but just how necessary is this compilation? It was only a little over five years ago when Forefront Records and Audio Adrenaline released Hit Parade, a greatest hits album that also featured 17 tracks, and truth be told, one of the better collections of its kind in Christian music as far as comprehensiveness and accuracy go. Eight songs—half of both albums—overlap between the two.

Spanning fewer albums, Hit Parade naturally did a better job of capturing Audio A in their prime, featuring more tracks from their best work. With Adios, you miss out on classics like "I'm Not the King," "Walk on Water," and "Underdog." Bloom, the band's bestselling album from 1996 and considered the favorite by most fans, is woefully underrepresented with only "Never Gonna Be As Big As Jesus"—that same album's "Man of God," a bigger hit on some charts, is conspicuously absent here. Perhaps Adios would have been better if it complemented Hit Parade rather than replaced it. "Good People" from Bloom and "Good Life" from 1999's Underdog are significant hits ignored by both compilations.

Instead of a comprehensive anthology, treat Adios as "the essential" Audio Adrenaline. It still features most of their best-known material, including signature hits like the psychedelic funk of "Some Kind of Zombie," the hip-hop stomper "We're a Band," the metaphorical rocker "Chevette," and, of course, "Big House," the classic youth group sing-along. "Hands and Feet" and "Get Down" are also rightfully included, though sequencing them back-to-back only shows how stylistically similar they really are.
