The Grammy Museum is opening a new permanent exhibit that puts the spotlight on the people who actually write the songs.

Tower of Song: Iconic Songwriters & Recordings opens May 28 in Los Angeles, bringing together artifacts from both the Grammy Hall of Fame and the Songwriters Hall of Fame. It’s a partnership that makes sense, shining a light on the craft behind the hits.

The crown jewels are wild. Kurt Cobain’s Mosrite Gospel guitar that he used to write most of Nevermind. Prince’s gold-rimmed glasses from Purple Rain. Miles Davis’s red lacquer trumpet. Keith Moon’s gold Premier drum kit from Tommy. Jim Morrison’s personal notebook. Frank Sinatra’s microphones from Capitol Records sessions.

On the songwriting side, there’s Neil Diamond’s handwritten lyrics for “Song Sung Blues,” Diane Warren’s Yamaha DX 7 keyboard she used to write countless hits, and the LinnDrum and Ensoniq synthesizer Jimmy Jam and Terry Lewis used to create Rhythm Nation 1814.

The exhibit includes an original film featuring Alan Menken, Carole King, Warren, and Jimmy Jam discussing their creative process. There’s also a digital interactive asking visitors to break down what makes these Hall of Fame songs actually work.

The opening night features a public program with Jimmy Jam and Warren breaking down their craft, followed by a reception.

For indie songwriters grinding it out, this is validation that the craft matters.
