One question about Genres another about Sublime?

Ska punk is a fusion of punk and ska. It has a ska beat with horns but also has fuzzy guitars and sometimes punk lyrics. Alternative rock is rock associated with a counter culture or underground scene. For example, grunge is alternative rock. Reggae is music derived from the islands that has a slow beat and usually includes steel drums, horns, and wah wah guitars. Reggae fusion is reggae fused with another genre of music. For example, some would say Sublime is reggae fused with rock.
