Classical ballet and contemporary dance

As the Royal Ballet rehearses Christopher Wheeldon's 'Alice in Wonderland', its first new full-length ballet in 15 years, Peter Aspden talks to Royal Ballet principal Tamara Rojo, Sadler’s Wells artistic director Alistair Spalding and FT critic Clement Crisp. Does 'Alice' represent a return to traditional values? Are ballet companies doing enough to encourage new work? And, what is the relationship between classical ballet and contemporary work?
