hello,

the idea is 'they tried to do something to prevent the concert from happening', like a mass protest, disorder, or in a more civilised way they can do it through legal means.

verb is сорвать концерт - narušit koncert? - basically 'prevent it from happening'.

or you can say Произошёл срыв моих планов. Мои планы были сорваны. - My plan was broken.
