Ska - Loved the British stuff, early 80's - Madness, English Beat, JoBoxers,
stuff that came out in the mid to late 90's just didn't hold water for me. Did see the Mighty Mighty Bosstones, they were great.
Mod - For me it starts and ends with the Yardbirds. The early Who stuff was great, think it was evident they were going to evolve as most great bands do. The Kinks and the Animals had some good songs in there as well.
