Sims Sessions: The Sims Event of the Summer

I think this will work like the festivals in City Living and Snowy Escape. You will get a pop-up notification and pressing the button will load your sim into the festival area. The npc sims will perform their songs on a stage, it will probably be similar to how the sims use the karaoke machine. When their sets are finished your sim can play the piano or sing into the microphone. This would have been great way to introduce drums but I am not getting my hopes up. Free stuff will probably be t-shirts with the artist logos and any new CAS created for the performers.
