Port Gorges calls its sound “indie funk fusion,” and you can hear it for yourself on Saturday night. The Portland band cites its influences as Celtic, Afro-Cuban, blues, reggae, pop and soul ,so you can expect an eclectic night of music. Hambone, also based in Portland, is a four-piece soul jam fusion act tinged with jazz and blues that’s opening the show.
