John Mellencamp has announced his 23rd album. Sad Clowns & Hillbillies comes out April 21, and Mellencamp will follow the release with a summer tour featuring special guest Emmylou Harris. (Rolling Stone)

Unfortunately, Harris won't be along when Mellencamp hits the Minnesota State Fair Grandstand on Aug. 29. Mellencamp is the second music act, and third entertainer overall, to be announced for this year's Grandstand lineup; Nickelback will play the fair's opening night on Aug. 24, and comic Jim Gaffigan is booked for Aug. 26.

Mellencamp was last in Minnesota to play the annual Starkey Hearing Foundation benefit at St. Paul's RiverCentre last summer.

Mick Jagger has a memoir — and we'll never read it

Publisher John Blake says he's obtained a copy of a 75,000-word memoir written by Mick Jagger in the early 1980s. Blake says it's a fascinating book, and likens it to "the rock 'n' roll equivalent of the Dead Sea Scrolls." He believes the manuscript was originally rejected because it was "light on sex and drugs." A spokesperson for the Rolling Stones confirms that Blake has repeatedly sought permission to publish the book, but Jagger steadfastly refuses to grant permission. (Billboard)

New guitar museum in Tennessee

A new museum that may become a mecca for guitar fans is opening March 10 in Chattanooga, Tennessee. "The Songbirds museum is the new home to what is considered by aficionados as the premier private collection of rare guitars in the world," reports USA Today. "The collection features approximately 1,700 significant guitars from the early 20th century to the 1970s." The museum will focus not on which musicians played the guitars, but on "the beauty, craftsmanship and significance of the instruments themselves."

Kate Nash vs. Snapchat

A recent Snapchat lens featured a clip of music that seemed to be taken from the 2007 single "Foundations" by Kate Nash — much to the surprise of Nash, who posted a series of social media messages asking, "Where's my paycheck?" Snapchat subsequently deactivated the lens, and said they'd made arrangements with a third-party company claiming to have legal rights to license the song. It's unclear whether that third-party company was in fact within rights, or even whether the sampled audio was actually from Nash's song versus a soundalike — but Nash was taken aback. (Mashable)
