As a VK reporter, I have three personal goals.
1. To introduce people to bands (& brands) they may not have come across yet.
2. To re-introduce people to bands they may have discounted due to a bad experience or misleading reputation.
3. To support bands who deserve world-wide acclaim for their talent and hard work.
Now, #1 was the impetus for projects such as the Indie Introductory Series and Final Fantasy interviews, and #3 is accomplished on a daily basis. The difficulty lies in #2.
We of the VK community are generally, by nature, a very opinionated people. We derive lifelong bias via first impressions and occasionally through second-hand perceptions. Now, you may be enamoured of a band or two and have no interest in others and that's your prerogative - though I'd consider it a shame. However, if you are constantly searching for new stimulation, I recommend taking a deeper look.
If you think you may have discounted a band unfairly for any reason, give them another chance. If there's a band you dislike because, for example, they're too poppy but you hear their onemans are actually very heavy, give that information a chance. Go to a oneman. Check out a live DVD. You may - quite likely, in fact - be pleasantly surprised.
If you hear that a band you disliked in the past has vastly changed, check out their new material. They've probably adapted and evolved beyond what turned you off in the first place.
Having strong opinions is not a detriment - but - it can greatly limit our joy in life. I speak from experience when I say there is at least one band out there you think you hate who could actually become one of your favourites or whose oneman live could turn out to be one of the most entertaining/stunning experiences of your life.
Don't take anyone’s word for it; experience for yourself. Once you've done that at least twice, then you can begin making an informed opinion.
For those who live overseas, sadly your choice of shows is limited. Your favourite band may never make it to your side. Yet there are plenty of bands willing and wanting to perform overseas if they could only identify a market who want them. That band whose CDs didn't grab you might just be religiously amazing live. Don't let that slip away. Don't like a band’s music? Read their interviews! You might get a feel for the priceless entertainment value of their shows.
