Veteran rock bassist Juan Alderete (a long-running member of veteran metal band Racer X who was also in The Mars Volta from 2003 until their 2012 breakup, has played with Mars Volta guitarist Omar Rodríguez-López's solo project for about that same amount of time, has been Marilyn Manson's touring bassist since 2017, and more) is sadly in a coma after getting into a "very serious bicycle accident" on January 13. His wife Anne broke the heartbreaking news on Facebook, writing:

Hi everyone - this is Anne, Juan's wife. While I generally hesitate to share personal details on social media, it felt right to include all of you who've supported Juan over the years as friends, fans, fellow music (and food, cat, bike, Japan) lovers and musicians.

Juan was in a solo (no cars, other people) and very serious bicycle accident on 1/13/20 not far from our home. He - as always - was wearing a helmet and protective clothing but sustained serious head trauma in the form of a Traumatic Brain Injury (TBI); his form of TBI is Diffuse Axonal Injury (DAI) and as of today, he remains in a coma.

The only prognosis is to wait and see, as the brain is a complicated organ and the outcomes for DAI patients has a range as wide as the sea. While frustrating, it also allows for a world of positive outcomes so we can only hope for the best.
We know you have questions, concerns, thoughts to share, so please feel free to leave them in the comments (not DM please, sorry) here. We're also very eager to hear from neurologists, medical professionals with experience in DAI and TBI, first-person accounts of similar trauma and outcomes - essentially any useful, factual and accurate resources that relate to Juan's injury. If you have any of these, please DM me (Anne) @tunatoast.

We will post updates here from time to time. Thank you all and please keep Juan in your thoughts. - xo, Anne

Our thoughts are with Anne and the rest of Juan's family and friends, and we're pulling for Juan.
