If you hear someone play and it inspires you, makes you want to play and learn, and makes you feel great- follow it. Go and learn how to do it, whether it is a lick, concept, song, or whatever.
If you hear a person play and it intimidates you because you can’t do that- it makes you feel small and worthless- ignore it. This can happen in two situations- 1.) the person is purposely trying to show off, or 2.) the person is just playing, not knowing they have that effect upon the listener(s). The first one is a sign of an immature individual (which can manifest in people of any age). This is bad musical vibes. Ignore that feeling and person. These people are most common in music stores, where they like to demonstrate all the complicated things they have been practicing lately to a captive audience.
In the case of the second, ignore those feelings as well and just listen. That person is different than you, and means no harm.
Always follow inspiration.
This is a short and sweet blog- my fingers either want to be on the guitar and not the computer, or I want to be outdoors and not sitting at the computer. Thus, I have not been very prolific in my blogging.
One other thing- listen to B.B. King.
I’m just saying.
