Amy Ray and Emily Saliers broke out big in 1989 with their self-titled major-label debut thanks in large part to the success of “Closer To Fine,” which is still a folk-pop classic to this day. Last month’s Poseidon and the Bitter Bug was a two-disc affair, half dripping with Mitchell Froom production and half consisting of more barebones acoustic renditions of the same songs. More importantly, though, it was a breaking point for the Indigos: with comparatively little fanfare, they ditched their label and joined the megalo-indie ranks of like-minded convention buckers like Radiohead and Counting Crows.
