i think the traditionally big markets don't have much of a sound anymore. LA is too much of a melting pot/relocation destination to have anything distinctive in 2021. NYC has been chasing trends to no avail for about 15 years. the drill thing seems like a trend too. ATL is pretty firmly in pop trap mode but i imagine there will be a subset to counter it. CHI had drill but no one since keef has really made a mark. bay area is indelibly bay area; feels like it hasn't changed since 2005
