On October 12, Brooklyn’s rock quartet, Blackbells, is welcoming their new EP, “IxI” into the music world with an early show (6:45pm doors) at Mercury Lounge. Accompanying the release (it is officially out digitally today.), the EP’s seductive, opening title track is a music video available on Baeblemusic. “IxI” features tracks that fans have been hearing and enjoying live for months, including sultry, hooking, and psych-rock-riff-ridden “The Shelf,” “Shoestring Lolita,” “Testify,” and “Bad Bones.” Tickets for tomorrow’s show are available for purchase here. –Meijin Bruttomesso
