There’s little more tiresome than those who complain that music ain’t what it used to be. Times change and people change — let alone vast, corporate-controlled industries — but the reasons to come together for making art and documenting a life are always within reach.

Indifferent to classification and rigorously do-it-yourself, the players in Portland’s folk group Big Blood have been evolving the reasons to make music for more than 10 years (and, considering their work in old Portland experimental folk group Cerberus Shoal, many more beyond that.)
