"El Cuarto de Tula" was composed by Sergio Eulogio Gonzalez Siaba (1916 - 1989). It is sung by Eliades Ochoa with Ibrahim Ferrer and Manuel "Puntillita" Licea joining Ochoa in an extended descarga (jam) section improvising lyrics. Barbarito Torres plays a frenetic lute solo towards the end of the track. Timbales are played by the 13 year old Julienne Oviedo Sánchez. .
