Exclusive: Pete Wentz Talks Mysterious New Black Cards Project

'Later tonight and this week there will be more of Bl4ck C4rds revealed,' he cryptically tells MTV News.

For a guy so used to talking about, well, everything, Pete Wentz has been rather tight-lipped when it comes to Black Cards (or, as he puts it, "Bl4ck C4rds"), the mysterious new project he's been putting together over the past few months.

So far, there has been just a simple blog post about the thing, which included a link to the new Black Cards website and a message from Wentz that "there will be no treasure hunt. [No] viral campaign ... just the opposite. Next week things will appear on this site in a very controlled distribution."

And he wasn't kidding. The site now features a snippet of one song — an electronic, Elfman-via-Mos Eisley Cantina composition featuring a female singer, reportedly called "A Club Called Heaven" — and on Monday, Wentz took to his Twitter account to promise that there'd be even more Black Cards stuff coming Tuesday night (July 6).

But other than that, he's played the Cards close to the vest, and he kept it up when MTV News e-mailed him for more information on the project, writing only: "Later tonight and this week there will be more of Bl4ck C4rds revealed."

Of course, we sent him a follow-up e-mail, one that asked him just who is actually in the group (former Chiodos frontman Craig Owens seems to be involved, since he posted a short video playing a snippet of the same song on Vimeo). More specifically, we had to know the identity of the much-discussed female singer, who some fans believe is Wentz's wife, Ashlee Simpson.

And, in keeping with recent form, this is how he replied: "Nobody is guessing right so far."

With that, the mystery continues to grow — until (presumably) Tuesday night, at least.
