Here is a look at two top music festivals:

***

Chicago Blues Festival

When: June 13-15

Tickets: Free; www.cityofchicago.org

Lineup: Billy Boy Arnold, Dr. John, Aaron Neville, Bettye LaVette, Willie Clayton, more

The skinny: This one belongs on the bucket lists of all big blues fans. It should be viewed as a necessary pilgrimage -- rather than a simple vacation plan -- by those who worship the music made by Muddy Waters, Howlin' Wolf and the Windy City's many other blues legends. The vibe is decidedly mellow yet joyful, as blues lovers from around the globe gather in Chicago's lovely Grant Park to enjoy food and drink, sun and shade, and terrific tunes. The lineup is always strong -- but the 2014 bill, highlighted by Dr. John, Aaron Neville, Billy Boy Arnold and Bettye LaVette, is the best one in years.

Bonnaroo Music and Arts Festival

When: June 12-15

Where: Manchester, Tenn.

Tickets: Passes start at $284.50; www.bonnaroo.com

Lineup: Elton John, Kanye West, Jack White, Lionel Richie, Skrillex, Wiz Khalifa, more

The skinny: It started out in 2002 as primarily a jam-band fandango and has grown into one of the most diversely appealing music events in the world. Some 80,000 happy campers will turn out to a 700-acre farm in rural Tennessee to commune with nature, party with fellow music lovers and enjoy some 150 live performances held on 10-plus stages. It's like Woodstock for the 21st century. Over the years, Bonnaroo has hosted such greats as Phish, Radiohead, Stevie Wonder, The Police and Bruce Springsteen. The 2014 lineup is a particularly nice mix of R&B, hip-hop, indie-rock, electronic dance music and other styles.
