Speaking of the Siren’s Song Tavern and shows whose start time promises a bit of evening sunshine over the nearby water, 8 p.m. is a good time to return to port to check out a very cool gig to help inaugurate your work week. Portland sextet Abronia plays longform, psychedelically- tinged soundtrack tunes fit for the vast deserts of the haunted mind. The band is joined tonight by two very fitting local co-conspirators, the excellent Cardboard and one of my all-time favs, Blackplate. This show is my undisputed pick of the week, and if you are a fan of outré soundscapes and heavy, frozen noise floes, this one is not to be missed. ($5-$10 sliding scale).
