For the lover of the “darker, rowdier, acoustic movement”, according to this listing in the SF Weekly. Looks like a good romp to me!
Light acoustic music with ties to bluegrass, country, old-time, and folk is more popular than ever in indie circles. But the flipside of this trend is far more compelling. In San Francisco, the leaders of the darker, rowdier, underground acoustic movement are the Pine Box Boys, a motley combo of players whose twisted vision mashes dirty American roots, B-movie horror, and a deep respect for all things Slayer. Independent from day one — with no interest in toning down its R-rated sound for family access — the Bay Area murdergrass quartet has managed to defy the odds, plowing its own DIY path for a full decade.
