a slight tangent to this initial comment.
i've noticed more variety and ability with Canadian musicians who come from a French background over their English counterparts, and i think the rural / urban angle plays a big factor in that, especially on the east coast.
it's not that one is better than the other but the English areas are more urbanized and rather than promote diversity it seems to have the opposite effect. musicians seem to become either too concerned with maintaining the integrity they had when they first started out that they don't branch out of their comfort zone as much or they end up getting too caught up in the scene - especially when they've been part of 'the scene' since high school.
on the flip side the French musicians tend to grow up in more rural areas and lack the 'big city diversions' their English counterparts have and in turn end up stretching out more and spending more time honing their chops.
on the more national level, you hear far more prog-ish raggae influence far more often in popular music coming out of Quebec than anywhere else in Canada where the bulk of the offerings stick to established methoRAB.
not exactly offbeat but an observation none the less.
