Guys, Does this sound like he asked me out on a low key date?

I was quite surprised, when he was mentioning this festival, he said I should play at it. I could play the piano overlooking the lake and he would play the harp with me. I couldn't even tell if he was being serious so I just smiled and no official plan was made. He just informed me when it was on and where , what happens there etc.
