fpr more modern ska music:
- Babyhead for something more experimental
- Capdown for something a little more mixed genre but with ska roots
However..
- Less Than Jake (as Alo suggested)
- Reel Big Fish
- Me First And The Gimme Gimme Gimme's
- Catch 22
are all fun lighted stuff!
Ska nowadays seems to have more inspiration from other genres like punk, rap, hip op, drum and bass and things like that now..
well.. enjoy!
Hope that helped you along your way!
