The Grammys’ 50-year history is just a jumping-off point for this museum anchoring the L.A. Live entertainment complex. Four floors of exhibits let visitors in on the creative and production sides of every type of music, from opera to polka to visual kei rock (it claims more than 160 genres). Interactive displays let you explore differences and connections between genres, mix your own track, and compare recording technology’s impact on sound quality. Depending on the rotation of temporary exhibits, you might see the latest red carpet fashions from the BET awards, Thelonius Monk’s baby grand piano, or Jim Morrison’s writing chair; two particularly interesting shows from 2014 were “California Dreamin’: The Sounds of Laurel Canyon 1965-1977” (think The Doors, Joni Mitchell, The Mamas and the Papas) and “Pride & Joy: The Texas Blues of Stevie Ray Vaughan.” Varied public events (such as evenings with recording artists) and educational programs (introduction to current DJ techniques) play as big a role as do the exhibits. Unless you’re here for a specific exhibition, plan to make at least one return visit just to scratch the surface.
