Bands like Reel Big Fish, Save Ferris, Goldfinger and Less Than Jake emerged with a punk with brass sound. Ska was not clearly defined anymore. The '90s cannot be pinned down as having one particular sound as have decades in the past. The '60s had British rock, the '70s had disco, the '80s had new wave, and the '90s has had grunge, punk-revival, electronica, gangsta rap, ska, among others. There is a glut of styles, and styles within those styles.
People have more varied tastes, and musical trends come and go quicker than presidential scandals.
Ska is more about a feeling. It's easy to play ska, but the good ska is that ska that hits you. Greg Lee, the Hepcats other lead singer, agrees. Ska is not easy. The way a lot of new bands play it is easy, because they're taking a ska-punk blend, and making it a hybrid.
