However, the same group expanded to a sextet in 1918, with Castillo now on guitar, Antonio Bacallao on botija and Óscar Sotolongo on bongos.

[2] Only two of the six recordings they made ("Mujer bandolera" and "Rosa, qué linda eres") have been issued on CD.

[4] In 1919, the discrepancies within the Sexteto Típico Oriental led to the departure of Ricardo Martínez, who was then replaced by Godínez.

[5] Thus, the founding members of the Sexteto Habanero were Guillermo Castillo (guitar and director), Carlos Godínez (tres), Gerardo Martínez (lead vocals and claves), Antonio Bacallao (botija), Óscar Sotolongo (square bongó) and Felipe Neri Cabrera (maracas).

By 1925 the band's line-up featured Gerardo Martínez as the new leader, also singing and playing double bass; Guillermo Castillo on guitar and vocals; Felipe Neri Cabrera on maracas and vocals; and two new members: Agustín Gutiérrez on bongó (replaced Sotolongo in 1923 and left in 1928), and Abelardo Barroso as lead vocalist and maraquero, both of whom would also play with the Habanero's rival band, Septeto Nacional.

[2] The group's recordings in the 1925 to 1931 era were made in New York City and originally released as 78 rpm singles, now available on LP and CD.

[11] In October 1929, a performance of the Septeto was filmed in Ybor City, Florida, for the movie Hell Harbor.

[8] In the early 1930s the band experienced important line-up changes, with Guillermo Castillo and Carlos Godínez leaving in 1934.

[8] The following year, director Gerardo Martínez left the band to form a new group, Conjunto Típico Habanero.
