I have a four-story nerd boner for Meshuggah, and I’ve never tried to hide it: I worked myself up into a proper lather over their previous Chicago show, and later declared it one of my five favorite live metal experiences of 2012. So I’m not exactly on the fence about whether to recommend their Friday concert at the House of Blues, even though front man Jens Kidman has been fighting an ugly flu (for at least one show last week he was replaced by a propped-up inflatable doll wearing a cutout of his face while the band played along to prerecorded vocal tracks).

But as it so happens, I have a bonus reason to tell you to go: Los Angeles inner-space prog voyagers Intronaut play first, supporting the forthcoming Habitual Levitations (Instilling Words With Tones), due March 19 on Century Media.
