A while ago Indieful Rock blogged that Galaxy Express, Vidulgi OoyoO, and Idiotape would be hitting up North American this upcoming March. They're planned to preform at South By Southwest (SXSW) and Toronto's Candian Music Fest (CMF), though so far only the CMF's website has updated to include the acts. Rumour says they're working on stopping by San Fransisco, New Haven, and Cambridge as well.
CMF has some stuff written up about Galaxy Express and an empty page about Idiotape.
