It has been a very sad past couple of weeks for the United States. Not only did we lose influential musician Tom Petty, but we also experienced a terrible mass shooting beforehand. This experience has shaken up many musicians and regular people alike as the events took place at a Jason Aldean concert. This weekend, we're seeing musicians all over pay tribute to Tom Petty and the victims of this shooting.

Jason Aldean on 'Saturday Night Live'

"Saturday Night Live" paid tribute to both Tom Petty and the shooting victims alongside Jason Aldean. Aldean performed Tom Petty's "I Won't Back Down" for the show's live opening.

Aldean was performing in Las Vegas at the outdoor event that the mass shooting occurred at. 58 people died, and nearly 500 people were injured. Aldean was horrified with the event and shaken up, to say the least.

Aldean spoke up about the tragedy on "Saturday Night Live," stating, "This week, we witnessed one of the worst tragedies in American history. Like everyone, I'm struggling to understand what happened that night and how to pick up the pieces and start to heal. But you can be sure that we're going to walk through these tough times together, every step of the way. Because when America is at its best, our bond and our spirit — it's unbreakable."

Musicians at Cal Jam '17

At a music festival in San Bernardino, California, Foo Fighters and Queens of the Stone Age honored Tom Petty and Vegas victims as well.

During their performance, Josh Homme of Queens of the Stone Age noticed a sign in the crowd and asked for it to be passed up. The sign had the words "Vegas Strong" on the front and the 58 names of those lost in the tragedy on the back. He held the sign above his head for everyone to see, giving a moment of honor before continuing with the show.

It is thanks to Foo Fighters than Cal Jam '17 even happened. Frontman Dave Grohl was largely inspired by Tom Petty's beliefs and music. Grohl was friends with Petty, who once even invited Grohl to join The Heartbreakers. Grohl and Homme attended Tom Petty's last concert at the Hollywood Bowl. It was an inspiring event, definitely one that neither of them will ever forget.

There's no better way to honor an amazing musician than to put on your amazing music festival and play your hearts out, and every musician at Cal Jam '17 played their hearts out. However, despite their friendship, Grohl did not have any comment on Tom Petty's passing.
