What Do We Do Now is the fourth solo studio album by Dinosaur Jr. frontman J Mascis, released through Sub Pop on February 2, 2024.

[1] Mojo called it "an LP of insight and empathy",[5] while Uncut felt that "the result is Mascis's most fully formed and direct solo set to date".

[7] Greg Hyde of The Line of Best Fit wrote that What Do We Do Now "has some interesting moments on its first side, but quite a bit of it does feel leaden and lacking in energy".

[3] Evan Rytlewski of Pitchfork stated that if the album is "less satisfying than Mascis' previous solo releases, it's because it has less to reveal.

Mascis has written so many songs about the same needs and frustrations—his failures to communicate, to be understood, and ultimately accepted—that they can't help but bleed together".
