Aristazabal Emi Chen Hawkes is the double bass player for the British indie band Guillemots.

She cites some of her influences as Ron Carter, Paul Chambers and Charles Mingus.

During an interview in the summer of 2006, it was also mentioned that fellow band member Fyfe Dangerfield had bought the Van Morrison album Astral Weeks for her (Richard Davis plays the upright bass on this album).

[5] On an episode of Never Mind the Buzzcocks, Fyfe said that Aristazabal had found the perfect note to give a lady an orgasm, but she wouldn't tell the rest of the band what it was.

[5] She wrote and performed the song "By the Water" from Guillemots' EP Of the Night, and sings lead vocals on the track "Last Kiss" from their 2008 album, Red.
