I want to know the answer to the following question:
One of the leading performers of the laiko genre is who?
All the background I'm provided with is that "The leading performers of the genre include Apostolos Kaldaras, Grigoris Bithikotsis, Stelios Kazantzidis, George Dalaras, Haris Alexiou and Glykeria.". Is that enough to answer the question?
