The bigger dance-theatre crews were less good at taking hip hop beyond its bravura enthusiasm, although one sly success was Frank Ejara.The Brazilian soloist mixed locking and popping to show how hip-hop music works in our heads.Visual and aural tricks were everywhere, as were some brilliantly boneless boogaloo moves. All phone cameras pointed his way.MORE ABOUTBrazilCombat Sports And Martial ArtsGymnasticsHip-HopSadler's Wells
