They are led by guitarist and songwriter José Manuel Aguilera, who previously and concurrently worked with Sangre Azteka, Jaguares, Cecilia Toussaint, Steven Brown/Nine Rain (Tuxedomoon), and more.

After the original lineup—Aguilera, Federico Fong (bass), Alfonso Andre (drums), all of whom were guest members of Jaguares with former Caifanes frontman Saúl Hernández—went its separate ways, a second version of the band included Santa Sabina guitar virtuoso Alex Otaola and the rhythm section of brothers Jose María ("Chema") and Alonso Arreola.

José Manuel Aguilera released a second project with Jaime López titled "No más héroes, por favor".

Bassist Alonso Arreola put out a mostly-instrumental album "LabA: Música horizontal" that features all the other La Barranca members as well as jazz musicians like Michael Manring, Trey Gunn, and David Fiucynski.

Alex Otaola released a solo project (also featuring appearances from La Barranca and Santa Sabina musicians) titled "Fractales" in August 2007.
