It could be the future, the issue is that none of the drill artists have the talent to take it there, I would love to hear a sample-drill album from an artist that has the ability to rap about more than a handful of subjects. It'd be hard
The other major problem are the common drill kits used have some of the most pathetic drums conceivable, just a soft, tinny high-hat and a flat snare - and its not that conducive to proper sample usage.
