Paulo Franco is a margin walker. The constantly gigging, bilingual Richmond singer and songwriter makes Graham Parsons-inspired Americana, incorporating his Colombian ancestry on his brilliant new CD, “The Last Card.” On an album featuring songs sung in Spanish and English, tunes such as the organ-seasoned ballad “Leaving the River City” and the honky-tonked strut of “Rolling Back to Raleigh” invoke the sing-a-long era of early-’70s FM radio. On “Catrina Y Su Calavera” and “La Estrella del País,” his seamless Latin country-rock assimilations shine with horn punctuations, vocal hooks and memorable melodies. Impeccably recorded and produced by Bob Rupe, Franco celebrates the release of his instant cross-cultural classic on Saturday, Oct. 15, at Capital Ale House. Opening are the Richmond old-is-the-new sounds Tin Can Fish Band and Rob Williams. The afternoon show runs 1-4:30. $10. capitalalehouse.com.
