Motley Crue appears to be gearing up for something.

On Friday morning the band tweeted a poster for a "Dogs of War" show taking place on June 30 at the Underworld club in London, noting that tickets will be available on Monday. The tweet also includes a 41-second clip of an unknown song.

According to a press release, Dogs of War is the name of both the new song and the band that will be performing on June 30.  "Motley Crue has not confirmed the rumors," reads the press release, "but everything is strongly pointing in the direction that this is Motley Crue performing a club show to 450 people under the name Dogs of War the night before their Wembley Stadium show that will take place in front of 90,000 fans on Saturday July 1."

The release also notes that "Motley Crue have been in the studio recording new music with producer Bob Rock in recent months and it is confirmed that 'Dogs of War' is the name of one of the new songs."

You can see the poster and hear the song clip below.

Motley Crue is currently set to appear in Switzerland on June 27, after which their tour schedule is clear until a July 1 date in London.

The band does have new music on the way though when it will arrive hasn't been revealed yet. "The three songs that I just got with them are so amazing," producer Bob Rock, who also produced their 1989 album Dr. Feelgoodsaid last month. "It was just the best time."

These will be the first new songs with guitarist John 5, who recently replaced Mick Mars in the band's touring lineup. "The songs are fucking heavy," John 5 noted in a recent interview. "I sound like a little excited kid right now, but they’re heavy and they’re mean. I can’t wait for them to come out. I’m just so excited."

According to John 5, the new music is close to being finished. "I don't know if they’re completely done but I would say they're like probably 98%," he explained. "It has to be mixed; it has to be mastered. … All I can tell you is that it’s heavy and it’s aggressive, and I think people are going to dig it because, talking as a fan, it's fucking badass."
