Exciting performance group.

I have been (Perfect tense. I didn't use past tense because that would mean you now stopped watching it) watching (continuous) Umebou's dance video on youtube since last week.
They often dance to J-pop music.
An exciting story is always in their performance.
They are (plural) common stories but they express it well in dance.
That's their originality.
I want to perform with them someday.
