Horse Jumper of Love thrive on patient and pummeling songs. Since 2013, the Boston trio of singer-guitarist Dimitri Giannopoulos, bassist John Margaris, and drummer James Doran have slowly stretched the fringes of indie rock across five full-length LPs. Their music unwinds with gutting emotional intensity thanks to Giannopoulos’ impressionistic lyrics and how the arrangements violently lurch from delicate to bludgeoning. Disaster Trick, the band’s new album out August 16 via Run For Cover, is their most direct and uncompromising LP yet. Its 11 songs tackle self-destructiveness and healing with jolting lucidity.
