I think this can help:

I'm very glad of hearing about you! We can surely be together at the concert on Saturday 21 July.

Kim says that he has no information around them not to keep himself away from Red Stone concert! This means perhaps he likes them but not as you're standing for them. So that the sentence below should have been omitted!

I thought that you are interested in "Red Stone" too, but your questions suggest me that I was wrong.

I really am a tough fun of them as you know that this gives me a motif to be going to tell you something about them immediately.

The band plays different kind of music, that's all rock, and it will be the last concert they've got in our country. I mean they're travelling around the world with hopping that their music could aggregate many amateurs.

At the concerts, normally, I love standing in the crowd because you can move and dance besides you're listening to the music!

But if you prefer sitting down, that's all right for me!
About time of having the meeting it's better to be at 4 p.m. instead of 7 p.m. What do you think?

I would be thankful to you for your offer of standing the night at your flat and it's gonna be great to spend the next day together.

What do you think about staying home at speaking and relaxing the whole day?
Thank you!
