SPOILERS AHEAD

They didn't really do concerts in S1 of WOW. According to Tecna in 2x01, "they've been touring the world for years now", setting S2 a few years ahead, and they've become successful pop stars. Venomya most likely came along as the Winx got more successful (hence why she came in S2, they were really popular among the people of Earth at this time) because she sensed they were fairies and assumed her "Music Critic - Venomya" form to infiltrate. Once she confirmed her suspicions, she revealed herself as Baba Yaga.

Tinker Bell and the Shaman have returned to good, and if there is a Season 3, I doubt we'll see any of the previous characters. Their story is practically finished as Neverland and it's inhabitants returned to good.

If their is a Season 3, it'll most likely focus on Baba Yaga's coven as the new antagonists.
