The song "Shabhaye Tehran" by Sepehr Khalse and Erfan, featuring Farshid, points to the strange days of Tehran. Erfan and Khalse note that while everyone is struggling through hard work during the day, Tehran's nights light up with parties and give color to the city:
All the days are dark, but the nights are the most colorful
One of the notable points of this song is that it marked the first official collaboration between Sepehr Khalse and Erfan following their track "Mehmooni Khodemonoun".
