Maybe some Prokofiev-Toccata or Sugestion Diabolique
Or maybe selection of Scriabin preludes from op.11 (this is good choice if you play after them some big romantic piece like Liszt-some of them are relaxing so you can take a breathe..)
Of course Bartok-Allegro Barbaro
or you can chose some Rachmanionv (some prelude, or Etude-tableaux, or Moment Musicaux)
And next year is Mozart year, but also Schostakovich (I think 100 year of his birth)- he wrote beautifull 24 Preludes, so choice is your..
