After announcing the news of their upcoming comeback and revealing member Krystal, Victoria, and Sulli's teaser photos, f(x) has unveiled Luna and Amber's teaser photos for 'Electric Shock'.

Although 'M! Countdown' aired previews of the last two members last night, the official teaser photos released are a bit different. Much like the previous members' teaser photos, Luna and Amber are also seen sporting the shocking blue colored contacts.

The title track of the album, also titled "Electric Shock", is reported to be an energetic and rhythmical electronic-dance tune with an addictive chorus. The song compares the emotions associated with falling love to getting "electric shocked".

As reported yesterday, the album will contain a total of six tracks ("Electric Shock", "Jet", "Zig Zag", "Beautiful Stranger", "Love Hate", "Let's Try") and will be available offline on the 13th following the online release on the 10th.

Stay tuned for the release of their more teasers, including a highlight medley of the tracks off the album!
