Really, the title says it all. Asia released this album at the tail end of the whole arena rock movement popularized by bands like Journey, Boston, and Foreigner. While their sound owes some to those bands, it also includes a number of truly visionary elements.
Listening to the album, I am constantly picking out sounds and structures that are still now being hailed as innovative. For example, for some reason I draw comparisons to Japanese metal band Sigh's opus "Imaginary Sonicscape", which was released in 2001 and praised for its avant-garde tendancies and innovation. In 2001. Nearly 20 years after Asia used these types of sounds and structures.
The opening track "Heat of the Moment" has become the band's signature tune, and for good reason; it's so amazing and catchy. On first listen, you will be hooked by the catchy guitar and vocal melodies. Upon future listens, you will realize how complex the song can be. The time signatures used are very unusual for rock music, and when they use typical signatures, they toy with things like accents instead (NOTE: not speech accents, obviously, but musical accents).
The rest of the tracks follow a similar pattern, which does, in the end, hurt the album as a whole. Nothing else really touches "Heat of the Moment", but they're all still innovative, catchy, and generally solid songs.
RECOMMENDED FOR: fans of Journey, Boston, Loverboy, Survivor, Foreigner, etc., fans of progressive rock like Rush, Yes, ELP, Dream Theater, fans of keyboard-heavy or avant-garde type music (while Asia obviously doesn't fit in this latter category, I still feel the album is rewarding to those types of fans)
