The Sons of Champlin, led by Bill Champlin, former member of the American iconic band “Chicago” are always musically evolving. The Sons started in Marin County in 1965 and have stayed true to their musical roots since then. The music of the band is R & B and rock based with lyrical content that connects the audience with the band. The reason for the longevity of the band playing together for all of these years become obvious within the first few notes of the first song and becomes clearer over the next couple of hours. While the band has revolved around Bill’s singing and song writing, he distributes the spotlight throughout the performance to showcase the individual abilities of band mates. There is now a triple threat with the addition of Tamara Champlin to the band.
