Days are Nights, brazilian darkwave band that sings mainly in portuguese (despite their name being in english).
As they've described their music in MySpace, "Days are Nights is a musical project that recognizes nowadays darkness, but is still able to see beauty. Therefore our sound is dark and beautiful, reflecting our days, which are the last". In August 2006 the band releases its first album, "Sounds of the end".
