Don't get us wrong: we still love "The Wire," "My Song 5" and "Days Are Gone." After a year and a half, we still haven't gotten sick of Haim's first album. But, well, it's time. After touring the globe, stacking up a truly impressive list of celeb BFFs and proving that the sisters are doing it for themselves on Days Are Gone, we were super psyched to get more proof this week that Alana, Danielle and Este are deep into sessions for their second full-length album.

Even better news? They're laying down tracks with the producer who helped hone their signature 1980s/new wave dance sound the first time around: Grammy-winner Ariel Rechtshaid. "Here we go again everybody," Este posted on Monday.

Truth be told, they've been working on the album for a few months, as evidenced by this post from November, with the message, "back to the start where we ended so long ago."

And all these sneak peeks:
