Troillo was Piazolla master.
Pugliese was old school tango (from the golden age) when orchestras composed for dancers.
Piazolla composed for the public who listened sat at an auditorium.
Usually milongueros likes more Pugliese and those who don´t dance like more Piazolla.
I suggest you listen to Troillo "Cachirulo", Biagi "La Viruta", Fresedo "Vida Mia", "Isla de Capri" or "Cordobecita", Calo-Veron "tristeza de la calle Corrientes" and Castillo-Tanturi "Bailongo de los Domingos" in order to have a wider perspective of the Tango Golden Age.
