In 1960 he created a talent agency and signed Otis Redding, a guy from his hometown of Macon, Ga. He then went on to do much bigger things. From Variety:
Walden would also represent Sam and Dave, Joe Tex, Johnny Jenkins and Percy Sledge during the '60s. In 1967, Walden asked Atlantic Records vice president Jerry Wexler to build a studio in his hometown. Wexler instead suggested Atlantic finance a record label based in Macon.
Christened Capricorn, the label quickly signed Jenkins and a then-little-known session guitarist working at Muscle Shoals Studios in Alabama, Duane Allman. Within two years, Allman had created the Allman Brothers Band, which released two studio albums with little fanfare. Their third disc, "Live at Fillmore East," was an instant classic, putting Capricorn on the map. The label had its first hit single with Jonathan Edwards' "Sunshine."
By the mid-'70s, with the Allmans leading the Southern rock charge, Capricorn had 27 acts signed to the label including Elvin Bishop, the Marshall Tucker Band, Cowboy and Wet Willie.
