One of my very favorite Humco bands is playing a gig to kick off its tour of the Pacific Northwest at Siren’s Song Tavern tonight at 7 p.m. Blackplate will be joined by Eureka quartet Dirt Magic in making a bit of sonic magic for the public’s pleasure. My buddy Sean from the first band tells me he’s not sure what the door price is but assures me $5 toward gas will go a long way.
