I saw Dos when I was 19 and completely lost in life. A big baby. I drove 2 hours to Santa Monica and then all I did was stand there with my thrift store shirt and my poser bowl haircut (the year was 1995) and stare at some beautiful girl in the crowd while K. and M. did their rabbit-hop dance on stage.
I got real bored. No drums. No noise. An intimate performance, two people on bass who loved each other in real life. Kissy-face, self-indulgent shit. I mean, I never heard their albums, so maybe they were good. Not that night, though. Not for me, anyway.
Afterwards, a bunch of people crowded around to kiss their asses. I hung out just long enough to give up on the cute girl and left, completely sober and alone. I don't know how the hell I didn't kill myself back then.
To answer the question posed in the thread: anything with alcohol in it. Nothing lite. Nothing fruit-flavored.
That's it.
