While Davie504 is not my cup of tea (in terms of contemporary bassists, I vastly prefer bassist Nathan Navarro's channel), he is one of the most visible and famous bassists out there. He's making bass cool for a new generation. If he's inspiring kids to pick up bass, then more power to him. If he's flipping the script on the cultural landscape and making bass the up-front, recognizable, lead instrument, I say great!
If I tell a kid I play bass, and they say, "Oh cool, like Davie504?" I'll take that over, "Huh, wha?" I say it all the time that I think younger generations are more familiar with bass and more attuned to it in their music than prior generations weaned on guitar.
And, hey, if Davie504 inspires people to delve deeper, maybe into Nathan Navarro's channel, then they'll uncover all the wonderful heroes we old-heads hold in esteem.
