Matchbox Twenty were a unique proposition for a late-'90s chart storm. While Rob Thomas' restless baritone fits in well with the post-grunge scene, the group's songwriting reflects a deep sympathy for classic rock melodicism and soulfulness. With folky guitars resting atop humming organ chords, “3 am” is one of the era's most elegant expressions of youthful angst. In the ensuing years, the group's pop craftsmanship has grown, enabling them to churn out pulsating alt-rock hits, country-tinged ballads, and everything in between.
