The Event Finder I linked to is more complete that the Honolulu Weekly, which mostly features stuff that is available on the mainland. Their attitude towards Hawaiian music ("duh"), when reviewing Kapono's is typical (admittedly tourist-oriented).
Mark, the average visitor is not looking for theatre, dance, etc. The Society of Seven is eclectic in performance, but it is the type of light entertainment most Waikiki visitors look for. 98% never get more adventurous than visiting Ala Moana Shopping center.
Events with good Hawaiian musicians and dancers never seem to coincide with a visit, good guitarist-singers never seem to have a regular venue and tickets for the best events must be arranged for well in advance.
On the Big Island, outside of the usual at the larger hotels, little can be found. If there is any activity at local watering holes, it is difficult for a tourist to find. Most performers hope that their cds and tapes will bring in some income (and performances at the rare auditorium shows). Hilo, now a sleepy backwater compared with its tourist heyday, has a little activity that may be found by asking someone at Univ. Hawaii Hilo (I remember a few years back, a friend in Hilo told me about the opening of a Safeway(?) store; everybody in town turned out for the big event of the year).

Out of the many thousands that come, thankfully few are willing to spend a weekend evening at the Pau Hana on Molokai (or similar) listening to a local group of Hawaiians playing for locals. Tourists are told to stay away from this and similar places. Personally, this is my idea of a good place at which to enjoy a very quiet holiday.
