Classic island music fans get a nostalgia night in Honolulu, with cheap tickets and an early window for locals.

• Troy Fernandez, a three-time Nā Hōkū Hanohano winner, is playing a Kaʻau Crater Boys tribute show at Blue Note Hawaiʻi.
• Two nights are booked: Thursday, October 29 and Friday, October 30, with an early and late set on Friday.
• Tickets run $25 through the venue — low for a Blue Note booking.
• A presale opens September 30 at 10 a.m. and runs to midnight; general sales start October 2.
• The draw is the ʻukulele-driven sound that shaped a generation of contemporary island musicians.

Outlook: Expect the presale window to move most of the seats, since both nights are small-room shows at a low ticket price.
