Jean-Henri Ravina piano concerto, Op. 63

[6bern6]

Hello.

Recently I've found the piano part of Henri Ravina's piano concerto, Op. 63, but there's no way I can find the orchestra.

The title also says that it is the "premier concert pour piano, avec accompt. de orchestre (ad lib)".  That ad lib is messing with me.

Would it mean there's no orchestra part?

And does anyone know of a recording ? I once saw a CD on amazon, but it was no longer available. I can no longer find the link, also.

The piano's part is this one :https://imslp.org/wiki/Piano_Concerto_No.1,_Op.63_(Ravina,_Jean_Henri)


Thanks in advance.
