Over the last decade, many bands have drawn inspiration from early-’80s British post punk. London’s Savages are yet more disciples of this dark, stark strain of rock that bristled and grimaced during Margaret Thatcher’s reviled reign.

Savages’ four women conjure a corn-free malevolence missing from much modern indie rock. (Neumos, 925 E Pike St, neumos.com, 8 pm, $15 adv, 21+)
