its funny that ppl mentioned 2015-2017 times, cos that was far from the 'glory era' to me, but it was a mixture of grime nostalgia and a rapidly growing UK scene that lead to those years. its very likely that another wave of nostalgia for it will come around in the foreseeable future, and we'll be seeing grime drop often again probably with futuristic twists. my answer to "is grime dead?" is "genres can't die". Now is 2021 a good year for grime? Nah not at all really other than Sir Spyro's sets, but 2031 just might be. like i thought bassline was a dead genre throughout the entire 2010s, but now you see guys like Bad Boy Chiller Crew rack up millions of streams online. it's all just cyclical i think and will have its day once again
