The location is Institutul de Etnografie și Folclor where there is a huge collection of romanian folklore songs.
Subcarpati and Argatu have managed to present romanian folklore in a more 'digestible' way for the youth and they have massive success.
Who would have thought that famous romanian folklore would make 50000 youths dance and sing very energetic at music festivals?
Listening to their songs will make you respect more your ancestors and your 'brothers', and love life, nature and people in general.
Please be careful when you put back the box so that it's completely hidden, and also can't be seen from above.
