Last Friday brought the annual outdoor music guide, which is always a frustrating endeavor because a few more events invariably pop up after deadline. And here's a biggie in some quarters: For the first time in three years, the Allman Brothers will be back at Walnut Creek. They had been the only act to play the amphitheater every year since it opened in 1991, a streak that ended because of Gregg Allman's 2010 liver transplant. They'll start a new streak on Aug. 4, with Lynyrd Skynyrd also on the bill.

Also new to the schedule is My Morning Jacket, Aug. 26 at the Downtown Raleigh Amphitheater. And here are a couple of concert series to add. First is Duke University's Music in the Gardens, which happens Wednesday (and one Thursday) evenings during June and July. This year's schedule goes like this:

June 6 -- The Beast + Big Band
June 13 -- The Old Ceremony
June 21 -- Dex Romweber & the New Romans
June 27 -- Bombadil
July 11 -- Mandolin Orange
July 18 -- Midtown Dickens with Special Guests
July 25 -- Megafaun

Tickets for the Duke series are $12, or $5 for Duke employees and students (and free for kids 12 and under).

Over in Raleigh, meanwhile, there's Oak City 7, with free shows along the lines of the old "Alive After 5" series. It will be every other Thursday evening between Memorial Day and Labor Day, on Fayetteville Street's City Plaza. And here's the lineup:

May 31 -- Tres Chicas, Antique Firearms, Saints Apollo
June 14 -- Katharine Whalen & Her Fascinators, Balsa Gliders, Nick Autry
June 28 -- I Was Totally Destroying It, Dark Water Rising, TBA
July 12 -- TBA, Chris Hendricks Band, The Broadcast
July 26 -- Annuals, TBA, LiLa
Aug. 9 -- Hobex, Jack the Radio, Paleface
Aug. 23 -- Big Daddy Love, Debonzo Brothers, Archbishops of Blount Street
