Any modern rock recommendations?

Ghost. Some songs are a bit heavy, which I like but have a kind of a classic rock sound.

More alternative than rock but one of my favorites is Beat Circus;

And Goose is influenced by Grateful Dead culture while being all original;

Try giving-- Nothing but Thieves -- a listen . 

Although I like all four of their albums . The first ( self titled )and their newest one

Dead Club City .  I feel are the best . Give them some time though .
 

I second this rec. Nothing But Thieves is one of the best bands to have emerged over the past couple decades. I find every track on every album is at least listenable. I rarely encounter that much talent in an artist anymore. I saw them live in Kansas City a couple years ago. They are every bit as good live as in the studio. 
 

I find they are somewhat a slow burn in terms of likeableness, however. They definitely have their own style, like grunge, pop, punk, yacht and ballad rock all rolled into one. My girlfriend didn’t like their music until we saw them live, now she “gets it,” and is a huge fan.
