Let's cut to the chase--I miss ska. If you've forgotten about this genre of music, let me talk to you about two of my favorite ska bands of all time:
The Mighty Mighty Bosstones--
If Fall Out Boy had been formed in the early '90s, they probably would've sounded like the Bosstones--an assimilation of hardcore punkers and a horn section, these guys are catchy as hell and their big single, "The Impression That I Get" is an example of fantastic music.
Dance Hall Crashers--
DHC was formed by Tim Armstrong and Matt Freeman of Operation Ivy and Rancid fame. They've got a dual-female vox front, great harmonies, and they bounce. DHC was originally a pure ska outfit, with a horn section, but they gravitated toward the punk side of things later in their career. They have a definite No Doubt thing going on, except they never wrote a ballad and they lacked Gwen Stefani's fashion sense so they never quite cracked the mainstream charts.
