I don't think I would describe The Concert as 'padding out' the mixed bills. Audiences in London had not been able to see any of Robbins' work for a number of years - it was only after his death that permission was received to stage his works at Covent Garden again.
I don't think the new season looks at all exciting myself, if anything it's even more conseravative than Dowell's programming. There are lots of the same classic works that we have seen so much of already (more Giselle, more R&J) and lots of performances of them. There is very little that is unfamiliar or new. The Forsythe works have all been seen here before, and I don't think they will look so cutting edge after Ballet Frankfurt appear here in November with more recent repertoire. The mixed bills are very repetitive with the same handful of works coming round again and again - it seems that the scheduling, and the pricing, rather assumes that ballet is a treat you see very occassionally rather than a regular habit.
The good bits are Onegin, a new Wheeldon, and Leaves are fading. We'll wait and see about the Duarto and Ek, but these really belong to the Rambert audiences, who are unlikely to pay ROH prices.
As regards Balanchine, it's not the Royal's native language, and the Agon this spring was tentative and very nervous. If that's the best they can do, then I'd rather see the Royal concentrate on doing its own native choreographers better instead.
