Brit prog-metal proponents TesseracT, an outfit noted for their exposition and mastery of a sub-genre of progressive metal called djent—wherein low pitch but high gain and hand-muting techniques produce the main guitar sounds—bring their Polaris North America Tour to Launchpad (618 Central SW) on Sunday, Nov. 29. Supporting these technically tight lads from Milton Keynes will be The Contortionist, an outfit straight outta Indiana whose work began with deathcore in the mid-aughts but has evolved into a progressive sound that is melodically subtle, rhythmically complex and spaciously executed. Erra and Skyharbor open the night’s 13+ homage to Geddy, Alex and the professor. JK. When all is said and done, these outfits have an expansive aural quality that should prove an apt and fulfilling end to the Thanksgiving holiday. Entry is a mere $15 and the music begins at 6:30pm.
