my problem is nuum being used as a theory. what bliss did was in no way pathbreaking or even revolutionary. it only seems that way because music crit is behind the music itself.
By the time you get to grime, the continuum doesn't end as such, but genres tend to owe as much to other continua as they do hardcore. dubstep is part of the continuum and so is funky but only axiomatically. jungle did not really owe anything to dub reggae, look at most of the samples they are ragga and digi dancehall. similarly garage had very little to do with dirty south, whereas grime did massively. And likewise bassline has a lot to do with the more euphoric end of harder northern house than it does grime.
By the time you get to funky you can even ask if the hardcore lineage is solely geneological by this point. it of course exists and no hardcore most probably would have meant no funky, but it was in no way consciously invoked by the producers, be that ideologically or in sonics. even the basslines are not really ragga. if people listen to afrofunk, highlife and soca they would realise that, but for some inexplicable (and no doubt slightly orientalist) reason, a lot of music pundits think anything remotely bassy has an explicit link to reggae and ja.
