In this edition, the orchestral accompaniment of Daniel Hellbach's Pop Concerto is arranged for a second piano. This helps the soloist to practise and helps orientation. Beyond this practical use, the two-piano version is a complete concert piece. Play-Along CD Every copy of this two-piano edition of Pop Concerto contains a play-along CD. There is a recording of the complete piece with a professional orchestra, but the CD also contains three versions of the orchestral accompaniment without the solo part, in three different practice tempos.
