PORTLAND — The legendary reggae group The Wailers will bring its trademark message of peace to Port City Music Hall on Sunday, Sept. 19, while on its U.S. tour.

Formed in Jamaica in the late 1960s, The Wailers went on to become the most successful reggae band of all time, selling 250 million albums.

The Wailers’ leader and musical director Aston “Familyman” Barrett helped forge the template for reggae with his booming, thunderous bass patterns. Family Man was also the right-hand man of former band leader Bob Marley, who died in 1981. He also played a large part in arranging Marley’s songs and co-produced a number of the late icon’s albums.

Over the years, The Wailers performed with Sting, Stevie Wonder, Carlos Santana, as well as reggae legends Peter Tosh, Bunny Wailer and Burning Spear. More recently, they collaborated with Kenny Chesney, Eve, Jason Mraz and Colbie Caillat, according to the band’s website.

The Wailers have contributed a new track, “A Step for Mankind,” recorded in Jamaica, to “Solution for Dreamers: Season 3,” the latest benefit compilation CD from Oniric Records. All proceeds from the track will benefit United Nations’ World Food Programme, the world’s largest humanitarian organization fighting hunger worldwide. The Wailers specifically focus on efforts to eradicate hunger in Ethiopia.

Duane Stephenson, The Wailers’ newest vocalist, wrote “A Step for Mankind” as a call for world unity and strength to support the ongoing struggle against world hunger. A songwriter renowned for his portrayal of love, culture and spirituality, Stephenson is recognized for many reggae songs, most notably for his work on Jah Cure’s reggae anthem “True Reflections.”

The Wailers will perform at 9:15 p.m. Tickets are $22.50 in advance, $25 at the door. For tickets, call 899-4990 or visit portcitymusichall.com/events/wailers. Port City Music Hall is at 504 Congress St.
