The Buckinghams are significant for two things. Their hit "Kind Of A Drag" was a monster, a huge smash that oozed kinetic energy and smarmy sensuality. More important historically, they were the immediate precursor of the group Chicago. The Buckinghams' producer Jim Guercia saw promise in the band's horn driven rock, and his vision eventually resulted the sales of millions of record albums (for Chicago, not the Buckinghams). The original group also hailed from the Windy City, and their bright, infectious sound yielded several more hits and memorable tracks. Sony/Legacy's Mercy Mercy Mercy (A Collection) has them all.
