If you go to one concert this week, make it: Roots rock royalty The Blasters, who bring their through and through “American Music” to Iota on Tuesday.

If you listen to one new album this week, make it: “Several Shades of Why,” the stellar new album from Dinosaur Jr. guitar great J Mascis. He’s always gotten his Neil Young on, and now he shows he can do it quietly, too.

And if you stay up late to watch one artist on TV this week, make it: One of the newest members of the Rock and Roll Hall of Fame, Alice Cooper. He’ll be inducted tonight and visit “Leno” on Friday.
