We made this observation this summer. You see, all summer Wild Pack took a different approach to our music, by turning all our gigs into jams. We thought it would help us grow faster as musicians. It worked. We found it to be the most fun we've had playing music. Some songs get left behind because of complexity, or odd progressions, but the standard progressions or classic favorites still work great. Of course, it all still has our Wild Pack flavor, but that's what we love Wild! And all of our gigs are a Pack of Wild Musicians having fun. It's been educational, motivating, invigorating and has made an impact on our approach to performing and playing music.
