Experimental composer Ned Lagin began composing Seastones during his time at MIT, building off of his love of free jazz and his studies of Renaissance music. But it took firmer shape through jams and recording sessions with various members of the Dead (Garcia, Mickey Hart, Phil Lesh) and other Bay Area luminaries like David Crosby and Jefferson Airplane’s Grace Slick. Originally issued by Jerry Garcia’s Round Records, it’s being reissued by Important Records. Lagin joined us to discuss the triumph and heartbreak of this pioneering electronic work.
