Wow, this thread is kind of old but very interesting isn't it!
If you're talking literally, well then, if I was blind I wouldn't have been online and would therefore never have discovered the existence of Jrock - probably. But I get the feeling that the OP was really asking "How important is the look to you?" which is a different thing... *nods*
I can honestly say that the appearance of the musicians makes no difference whatsoever to whether I like or dislike music. So, supposing that I was blind and I had a friend who could introduce me to various bands; if that was the case, the bands I would like would be exactly the same ones I enjoy now.
There was one case where I listened to a band because their look caught my attention. That case is SID; as it happened I liked their sound and I continue to listen to them. :music: If I'd been introduced to them by their music first, I'd still have liked it.
For many bands that I listen to, I have honestly no idea what they look like.
Equally, I listen to a lot of bands that don't have a visual element to their presentation, or at least, no more than all bands do (even 'plain' looking bands, such as boy bands, and those who dress in casual clothes, have some consideration of their visual image in presentation to the public!
).
I haven't read through this thread from the beginning, but people on this page mentioned non-Japanese music that they listen to... I like to listen to music from various different countries (the language doesn't make any difference to me, so I'll just go by whether I like the sound). I have a lot of CDs of 'old-style' British and American rock and metal (probably most of my collection is these, as that was the first style which got me interested in music other than classical). There are so many countries it seems like an impossible task for me sometimes to find out about everything I want to investigate!
At the moment I'm particularly enjoying discovering French bands.
I also like various Scandinavian metal bands, plus Rammstein
haihai: ) and Moonspell (who are Portuguese). In addition I'm discovering other British and American bands all the time. I have an increasing interest in industrial and electronica, which is leading me in American music at the moment. But my investigations change all the time...
