The dances of Mauro Astolfi, Spellbound Dance Company’s artistic director, recall a neverending loop — a kind of choreographic Mobius strip winding perpetually back to its beginnings.
That is not to say that the three works on Friday night’s Celebrity Series program, a Boston debut for this Rome-based troupe, didn’t astonish with their pyrotechnics. The nine dancers’ undulating torsos and cantilevered limbs, their roiling hips and rubber-bodied couplings make your jaw drop. But a necessary tension is missing from most of these works: they are horizontal, flat, rather than building in structural and kinesthetic intensity. The remarkable becomes humdrum when it has nowhere to go.
