Any modern rock recommendations?

Rival sons, the struts, blackberry smoke, tedeschi trucks

The Pretty Reckless are fantastic especially if you're looking for some great, old school, bombastic rock and roll. I like Big Thief. Can get heavy into their lead singer's soft vocals but can produce some driving rock like 'Not' at times. Really nice, basic four piece garage rock. You have The Illuminati Hotties and their 'tenderpunk'. Sharon Van Etten. Pom Pom Squad gets points for dark humor with an album titled Death of a Cheerleader. If you like the sound of Pink Floyd who are definitely not heavy metal rock and rollers, you might like curiously enough Lana del Rey. Songs like Venice Bitch with their lengthy, spacy instrumental passages remind me of Floyd. 

Whiskey Myers and Blackberry Smoke are about the only two I know of. I’m 70 so I’m of the 1964 to 1974 was the best music era.

All,

I've been starting to work thru the suggestions.  I've heard some pretty good stuff, but so far nothing that is exactly what I'm after.  I suppose I need to build a spreadsheet to keep track...I'll post another update next week.  Thanks!
