‘Rainforest’ to Sub for RhythMatix

Visa problems have forced Canadian dance troupe the RhythMatix to cancel performances Sunday at the Orange County Performing Arts Center in Costa Mesa that would have concluded this year’s Imagination Celebration, center officials announced Friday. In its place, David Taylor Dance Theater’s piece “Rainforest” will be held over for two additional performances. Refunds will be offered to ticket holders who do not wish to see the substitute show. The rescheduled shows will be at 1 and 4 p.m. in Segerstrom Hall. Information: (714) 556-2787.
