MINOR HEADACHE | The hangover from Tuesday night’s theatrics will have by now faded, but the one everyone got from the high of ’90s indie-rock sure beats on. You may think to nurse it tonight, in Portsmouth, where the totally decent rock bands SUPERDUDE, the NOTCHES, and CHANDELIERS — the latter a Boston trio playing a still-thrilling variant of noodly punk stuff — huddle together at the Red Door. January 2 is one of the coldest, socially distant days of the year, a sobering day of slicing through bullshit, deep introspection, and comfort food. If you wrap all that up by 8 or so, head to 107 State St in Portsmouth, New Hampshire. $5 cover. 603.373.6827.
