Blues music is about the realities of life. It expresses the ebb and flow of our human emotions, focusing mostly on the melancholy. When we’re sad, we have the blues. When we want to move away from that sadness, we can chase the blues away with music. Musically, it’s the famous 1-3-5 chord progression and a call and response lyric. But here on Nantucket, we’re often chasing the blues and trying our best to catch them. Never more so than this August, as the inaugural August Blues fishing tournament is ready to hit the Nantucket inshore fishing community.
