This weekend, New Hampshire will again be blessed with the presence of They Might Be Giants, founding members of the geek rock movement. (Geek rock being code for “people who are brainier than us and play music.”) Saturday, March 29, TMBG will play two shows at the Music Hall in Portsmouth. The first concert is geared toward little geeks, as TMBG will be performing their original children’s material, and then later in the evening, they’ll rock the older crowd with favorites, plus songs from their latest release, “The Else.” In preparation for the show, we’ve compiled a list of information you may not know, to saturate your brain, compiled from the countries mentioned in TMBG’s song “The Alphabet of Nations” from “Here Come the ABCs,” an album of original songs about the alphabet.
