The Ides of March are best-known for the tough, "hard rock with horns" sound of their 1970 hit "Vehicle," but that's just one facet of the group's body of work. In the mid-'60s, they played garage rock with a dash of folk. Their early-'70s albums found the band exploring psychedelia and progressive rock, while their later albums were steeped in soft rock and country rock. After returning to the studio in the '90s, the Ides of March beefed up the guitars and used contemporary hard rock as their guide, while still using brass for emphasis and impact. Despite the group's longevity and periodic creative turns, the four core members who formed the group remained at the helm through a career spanning six decades.
