Join the fan club. Members often are privy to a pre-sale of the best seats in the concert. Many fan clubs allow a limited number of members to purchase meet and greet passes, while others give away the passes via a drawing.
Listen to the radio station that is sponsoring the concert. Radio stations and other sponsors often give away free seats and meet and greet passes to the concert. They generally will announce to the listeners the times to call in to win the passes, tickets, t-shirts and other concert memorabilia.
Visit the websites of the concert's sponsors. For example, a beer manufacturer or carbonated beverage website may be sponsoring the tour for the artists and have passes available.
Purchase the meet and greet passes from someone who is not going to use them. Watch the newspaper for classified ads, online auction sites or college or community center bulletin boards. Many people acquire the passes and find out at the last minute that they can't attend. Keep trying until the last minute. Others acquire the passes with the specific purpose of selling them at a steep price. Determine what price you are willing to pay before dealing with these people.
