This is a good topic. I personally believe there is a lot to be said for not over-saturating your market. This holds true for both rotation bands and destination bands (a rotation band is a group that plays in a bar, and their audience is based on the bar’s natural draw. A destination band is where you show up at the venue because you want to see THEM.)
A lot of professional management companies that represent destination bands (which Jimi Hendrix was) have a clause in their contracts that they won’t perform within a 60-100 mile radius of venues, because it causes the concert promoters to have to compete with each other over the same act. Its a conflict of interest.
The one exception to this is musicians that specialize in certain areas. If Renato Neto, Andy McKee, or Valentina Lisitsa played multiple concerts in my area, I’d go watch them as many times as I possibly could because their musicianship is at such an incredible level, I could really learn something every time I watch them. I wouldn’t say the same of Eric Clapton or Jimi Hendrix, though I’m sure many others would.
In my experience, I’ve found it’s not the same. In college, you’re required to attend a certain number of professional performances per semester. The reason for this is that you learn and retain more information, and different information from subjecting yourself to the challenges of observing a musician in an environment different from the recorded performance (as in being there vs watching them). You also retain more information because of observing with the addition of a visual stimulant. You’re watching them in addition to hearing them.
For me this hinges on WHY I’m there to see them, and how much I get out of watching them. More specifically (for me), does watching them challenge me to grow as a player? Do you walk away understanding something you didn’t understand before about the musical arts? Or about the rhythm…chordal harmony…or about technique? I can watch Renato Neto or Jordan Rudess over and over, and observe an insane amount of originality and creativity in how they blend and layer sounds on a keyboard. I wouldn’t get that from having watched George Duke or Brad Paisley, even though they’re arguably just as good of musicians.
Long story short, it doesn’t have anything to do with the player. It has to do with you. What parts of their musicianship and their performance do YOU identify with? What do YOU get out of it? No correct or incorrect answer. Its just all about what you want.
