The website was made on Wordpress???
Maybe the hack didn't affected the database.
Happened once with me and i recovered everything without having to use the database backup.
The hack affected my theme files and i deleted them and reuploaded again.
If you need help let me know.
I'm not sure if i remember all steps i made.
But i can try to help.
Good luck on this....
Just for fun... the new music is great!
Sorry
