[15] Writing for Clash, Josh Gray said: "Much like their 2018 debut 'Street Worms', 'Welfare Jazz' concerns itself with the internal lives of the scuzziest dregs of humanity: no-good drifters who lug their vintage calculator collections from couch to couch, self-deceiving junkies who regale hallucinatory conversations they have with their dogs with the listener, alcoholics who scream and ramble on about their problems and other assorted bottom feeders.

As Viagra Boys have done on previous releases, Welfare Jazz also features a handful of interludes, a breath of fresh air from the smoky, heavy din of its basement mosh pits."
