The sisters of the pop-rock band Haim, who are all multi-instrumentalists, began as members of a family cover band, and have since jelled into a unit that is as synthesized as it is referential. The trio’s repertoire includes hooky Americana influenced by R. & B. (“Days Are Gone,” from 2013), the soft rock of the eighties (“Something to Tell You,” from 2017), and just about everything else on the monumental 2020 album “Women in Music Pt. III”—electro-pop, funk, country rock, even reggae. The band’s new album, “I Quit,” produced by Danielle Haim with Rostam Batmanglij, is even more eclectic, if a little chaotic—representative of a band that is eager to do everything and too talented not to try.—Sheldon Pearce (Madison Square Garden; Sept. 8.)Dance
