The "Omar Rodriguez-Lopez Quintet" is a side project of Rodriguez-Lopez. Taking some free time out of his busy schedule with The Mars Volta, Rodriguez-Lopez plays live shows with his quintet, which in 2005 included three members of The Mars Volta Group: Juan Alderete, Marcel Rodriguez-Lopez and Adrian Terrazas-Gonzales. The self-titled album from 2005 was recorded mostly in Amsterdam. The album, Omar Rodriguez, features long, improvisational songs with Dutch titles and no lyrics. Read more on Last.fm
