Robyn, photo by Amanda Koellner Live music whips up one of life’s more delicious neurochemical cocktails. Ingredients include endorphin-fueled euphoria, serotonin’s role in mood regulation, arguably the best oxytocin you can get while keeping your clothes on, and of course the fan-favorite feel-good chemical: dopamine. Big fan of that whole situation. In my mind, then, to be blessed with a concert to ring in a New Year is the best gift one can be given on December 31st.
