Berri Txarrak
A basque metal (early) rock (later) band that HyperChondriacMuser really loves, and thinks that they need more recognition. Apart from this...
Berri Txarrak (Bad News in English) is a Navarre rock trio whose songs are sung in Basque. It was founded in 1994 in Lekunberri, Spain. Their most known song is Denak Ez Du Balio, which features additional vocals from Rise Against's singer Tim McIlrath. More info here.
And what kind of correlation have this band with Muse?
Well, the singer stated that he likes Muse, and they cover Time Is Running Out at least three times in 2006. Listen here.
This band also meets Matt Bellamy in 2004 on a show they did at The Garage, in London... so technically Matt Bellamy went to a Berri Txarrak concert even if he don't know who are them anymore.
Fun fact: a couple of days after creating this page, the band was announced as a supporter at the MTV World Stage (Bilbao) gig. What a great coincidence.
