The Hot Sardines sound – wartime Paris via New Orleans, or the other way around – is steeped in hot jazz, salty stride piano, and the kind of music Louis Armstrong, Django Reinhardt and Fats Waller used to make: Straight-up, foot-stomping jazz. (Literally – the band includes a tap dancer). They manage to invoke the sounds of a near-century ago and stay resolutely in step with the current age.
