Andrew, Eddy, thank you very much for your very practical advises!
@Andrew: I didn' know that there are arrangements of concertos for solo piano! Thank you for the information.
This recording seems to be the realisation of that arrangement: http://www.youtube.com/watch?v=QqqKQILSr44&feature=player_embedded#!
@Eddy: In case of solo works there are many recommedations which edition is better etc. Is there a special reason that it's not the case with concertos? Just wondering.
And what are "arabesque figures"? I googled with those words, found some usages, but not the meaning or examples
