I never was a Volta fan but the last album (Which can be listened in
the Mars Volta's myspace page) sounds quite listenable and catchy most
of the time. 3.5 star album.
One of my favourite songs in the album is Asilos Magdalena with the
satanic lyrics combined by elegant acoustic guitar. However, once the
"Estrella de la mañana" vocal gets the distortion, some out of place
guitar dominates and it just sounds completely horrible!

Seriously, it sounds like an amateur guitar player in a Guitar Center
trying to solo without thinking what notes come out. To add insult to
the injury, the guitar tone has to be the most unpleasant tone I've
heard in a studio album. The worst part has to be that double guitar
near the end of the solo.
What are your opinions?
