The ninth annual Hallowbaloo Music & Arts Festival returns to the Hawai‘i State Art Museum as a ticketed event on Oct. 29, with Erykah Badu as its headliner.

Badu, performing as DJ Lo Down Loretta Brown, will headline the Hallowbaloo Street Festival, taking place on the grounds of the HiSAM and on surrounding streets. The 45-year-old artist has released one mixtape and six albums, most recently “New Amerykah Part Two” (2010). Her debut album, “Baduizm,” earned a Grammy Award for best R&B album in 1998, a year when she was also awarded the Grammy for best female R&B vocal performance. She won additional Grammys for best rap performance in 2000 and for best R&B song in 2003.

Club Hallowbaloo is expanding to include Nashville Waikiki at Aloha Tower Marketplace, along with multiple Chinatown venues, with complimentary trolley service connecting each area.

In addition to Badu, Hallowbaloo 2016 features national artists Iyeoka, ​Charlie Hunter & Scott Amendola, D Sharp (resident DJ of the Golden State Warriors), and local performers including Samadhi Hawaii and ​Quadraphonix.

Presale tickets, $15 and $80 VIP, go on sale Wednesday at 10 a.m. at hallowbaloo.eventbrite.com.
