Great thread!
Admittedly, if I know a musician is technically proficient, I’m more likely to give them the benefit of the doubt when I’m listening to them. But it also very much depends on the style of music. If I’m listening to a style that typically requires a high level of proficiency, like Progressive Metal, then I very much care, because musicians that aren’t technically proficient playing that genre end up just sounding like a slower, sloppier version of everyone else.
In other genres, the technical proficiency is largely irrelevant. A genre like Ambient or Doom are a lot more about the atmosphere and melodies and are often much lower tempo. Hell, some of my favorite artists in this genre, when I’ve seen them live, are technically mediocre at best, but that’s just not their goal.
Again, this is similar to the above. What is the message that the song is trying to get across? Sometimes technical proficiency is absolutely necessary, sometimes it’s irrelevant, but there’s a lot more gray area here. In general, if a particular theme can be down with greater technical challenge with equal emotional impact, then I’ll prefer that. In some cases, though, there’s a degree of trade-off, and in a case like that, a successful song is one that I feel strikes an ideal balance. Unfortunately, sometimes and otherwise great song is ruined when that balance is missed, especially when the artist feels they have to prove something and make a song more complex than it really should be.
So, I guess, for me it’s more like I evaluate songs with both the emotional impact, melody, and all that stuff on one axis, and technical proficiency on the other. An ideal song rates highly on both axes. But for a song where that’s not possible, depending on which part is more important, it should still try to maximize those values within that.
I love it. Sometimes I’m not really looking to be moved or for a particularly enthralling melody, and I just want something intellectually stimulating or something that blows my mind. And, of course, being live at a concert watching a musician play something that is technically challenging is an awesome experience.
