Honolulu's long-running slack key guitar festival is back this Saturday, good news for local music fans looking for a cheap night out.

• The 44th annual Hawaiian Slack Key Guitar Festival takes place at the Waikiki Aquarium, starting at 5 p.m.
• More than a dozen musicians are on the bill, including Ledward Kaapana, George Kuo and Jeff Peterson.
• Tickets are $15 for kama'aina, and children 12 and under get in free.
• The low price and the open-air aquarium setting make it one of the more accessible cultural events on the island this summer.

Outlook: Expect a strong turnout Saturday evening, with the festival continuing its run as a yearly fixture of Hawaiian music.
