Bastille's "Pompeii" is iTunes single of the week which you can download for free. Remember, the band just released their new EP, Haunt on Tuesday, which you can also purchase on iTunes. Also, the band's show at the Troubadour in California sold out in three hours last week.
Bad Blood is easily the best pop record released this year and "Pompeii" is so mindnumbingly catchy, it hurts a little bit. Their live set is phenomenal as well...this deserves to be their year with how good they are. Kinda curious as to when the record comes out stateside though.
