Last summer I have been on concert my favourite rock band AC/DC.
It was the best music event what I have ever been.
They played 2 hours gorgeous music, among other Highway to hell, TNT and others. Brian Johnson between songs told many interesting stories from his private life.
I was there with my friend Andrzej. We sat very near stage. After everything I did yourself photo with whole band. I would like sometime go again on their concert.

Last summer I was at the concert ("concert" czemu złe słowo ?) my favourite rock band AC/DC.
It was the best music event I have ever been to. (nie wiem, co mam dać zamiast "what")
They played 2 hours' gorgeous music, among other Highway to hell, TNT and others. Brian Johnson told many interesting stories from his private life.

Wybacz ale nie rozumiem co masz na myśli z tym "between songs".

I was there with my friend Andrzej. We sat very near the stage. After concert I took photo with the whole band. I would like go again at their concert sometime.

zlym slowem bylo 'on'
nadal nie tqorzysz dopelniacza - jak napiszesz: 'koncert ulubionego zespolu'?
zamiast what daj that, ale to mozna pominac, czyli przypadkowo masz dobrze
nie o ten dopelniacz chodzilo. Masz napisac 'dwie godziny muzyki'
brak przedimka przed concert, photo
nadal brak slowa przed go
nie 'at'.
'znowu' mialo byc w innym miejscu

Teraz jest dobrze ?

'among other Highway to hell, TNT and others.' ja bym coś zmienił
