Live 105 has announced the lineup for its second Not So Silent Night concert — and it's absolutely mammoth.

Arcade Fire, Phoenix, Alt-J and Lorde -- four of the most popular acts in the alternative-music universe -- will perform on Night 2 (Dec. 7) of the radio station's holiday gathering at Oracle Arena in Oakland. Other acts on the bill are Alt-J, Bastille and the Neighbourhood.

The lineup for Night 1 (Dec. 6) was previously announced and the headliners are Kings of Leon, Vampire Weekend and the Queens of the Stone Age. Filling out the lineup are AFI, Arctic Monkeys and Capital Cities.

"This is, by far, the biggest (Not So Silent Night) we've ever presented," says Aaron Axelsen, Live 105's music director and assistant program director.
