L'Via L'Viaquez is the second single from the album Frances The Mute by The Mars Volta. It is featured in Guitar Hero World Tour.
There are three guitar solos, all of them are moderately hard, although there are hammer-ons, pull-offs, and slider notes. The song is partially sung in Spanish, however the slower sections are sung in English. The drum sections are somewhat challenging, but they shouldn't be too much trouble. the latin breakdowns are the most challenging bits, and require fast hands to be able to complete. This is also one of few songs in the game where the bass is harder than the guitar, hence why it's in the 17th tier on the bass and only the 10th on the guitar. The bass features heavy use of the open strum in conjunction with regular notes, so be careful. The breakdown sections are essentially a cooldown period for the verses, so save up your star power for when the bassline can overwhelm you. On Medium, however, there are no open notes, so it's fairly easy.
