Every show in this more closely curated Fringe alternative will be making its U.S. or world premiere, with an emphasis on dreamy dance-theater pieces — like Bill Connington’s Hamlet-Oedipuds-Dracula-Satan hybrid Princes of Darkness or tl;dr’s experimental history of the Broadway Grand Hotel leading up to the day it collapsed in 1973 — and gleefully geeky genre exercises like B.J. Sebring’s 50s soundstage musical comedy Dollface.
