Foo Fighters Fenway Park 2017

CAMBRIDGE, MA - It's been over two years since Dave Grohl and the Foo Fighters descended on Boston for their first ever show at the fabled Fenway Park. As part of the "Broken Leg Tour", Grohl played guitar and sang on a Guitar Throne that allowed him to continue the band’s world tour after suffering a broken leg in its earliest days.

Since then, Grohl has fully healed and the band released a new album, Concrete and Gold, in September. Last week, the Foo Fighters announced two shows to support the album at Fenway Park next summer on July 21 and 22. Tickets to see Foo Fighters at Fenway Park in Boston went on sale today.

To get fans excited for the tour and casual listeners caught up on the band, we've put together a list of things you should know about Foo Fighters below. Enjoy!

1. With the release of their Saint Cecilia EP Grohl announced the band would be on a long hiatus in November of 2015.

Grohl penned a long letter to fans that tracked the Sonic Highways journey, detailed his gruesome leg injury and paid tribute to those killed in the Paris terror attacks.

"It was heartbreaking to leave that place, to say the least. I honestly feel like we left a piece of our band there as we were being torn away from it," Grohl wrote. "The perfect unity of life, and love, and music is something that only comes around so often and in certain circumstances. When you feel it coming on, you have to take hold of it. That place and those people made it possible for our band to take one, big final breath before the curtain closes. Thankfully, we have evidence of this in these songs that we’re giving to you today. "

2. Keyboardist Rami Jaffee is the Newest Member of the Band.

Though keyboardist Rami Jaffe has performed and recorded with the band dating back to 2005's In Your Honor album, he's not been mentioned as an official member. But with the release of "Run," Jaffe was included in the band photo and Grohl made a point to mention that there were six members in the band during the interview.

3. Concrete and Gold was Produced by Greg Kurstin, Who Produced "Hello" for Adele.

"I wanted it to be the biggest sounding Foo Fighters record ever," he said. "To make a gigantic rock record but with [producer] Greg Kurstin's sense of melody and arrangement... Motorhead's version of Sgt. Pepper... or something like that."

The band's first trip into the studio with Kurstin came after Grohl was driving around four years ago listening to "Again and Again" by Kurstin's band The Bird & the Bee.

4. The Election of Donald Trump Inspired Grohl to Write Concrete and Gold.

“I look at all of the different periods of time where I’ve written lyrics, and they all have their own references and different phases,” said Grohl. “This one came out pretty clear: I’m a father now, I have to consider a lot more than I used to, and I think I’ve realised we’re not all as free as we were before. In every way. I mean, as the political arena started heating up in America before the elections, it became clear that there was so much more threatening all of our lives than I’d considered before.”

Grohl continued: “I’m looking at a candidate that has blatant disregard for the future environmentally, when it comes to women’s rights, diplomatically…I have three daughters that are going to survive me for decades – how are they going to get on unless there’s some positive and progressive change?”

5. Boyz II Men’s Shawn Stockman Collaborated On the Song “Heavy”

Grohl said that he ran into Stockman in an unidentified parking lot and asked him to sing on the Foo’s album. Stockman lent his vocals to Concrete and Gold’s “heaviest song.”

“It sounds like Sabbath and Pink Floyd…It’s the last song on the record,” Grohl added. “He built a choir – it’s like 40 vocals stacked. It’s insane. It’s amazing.”
