Phish is the 1st that pops in my head, but the caveat for any of these situations is that none of the folks I was hanging were really trying to get me like the stuff outside of the initial introduction. On old friend, however, really clicked with Phish and definitely thought I'd like far more than I did. I dig a handful of tunes, only two of which I know by title.
I remember feeling a bit browbeaten by folks I was hinging with that were stuck on one band for periods of time. To that, I never got into NiN, Soul Asylum, so much hip hop, metal heavier than Testament (or any metal w/ Cookie Monster vocals, Pantera (as good as Darrell may have been as guitarist, I didn't like Phil's vocals--not liking the singer is always a deal breaker), but not much else.
On the flip side, I've tried to share new music w/ my dad over the decades (given that he really informed so much of my musical likes/dislikes), but I don't think he's ever appreciated any of it. He emphatically disliked a band I love that reminded me very much of the Band and Neil Young (without being obviously derivative thereof), two artists I know my father loves. His response to hearing less than a handful of Avett Brothers tunes:
"If this music were around in late '60s, we'd still be fighting the Vietnam War."
I'm not sure what that really means, and I acknowledge that it's a solid burn in its inanity, but really?
