James Bond’s creator, Ian Fleming, once surmised that Diamonds Are Forever. English great Shirley Bassey would surely agree, but let’s not forget Paul Wall. The Houston word-bender cuts a sharp picture these days, lean and grinning ear-to-ear with a grill that looks like 1,000 rodeo champion belt buckles or a row of Super Bowl rings. Rave rectors Ghostland Observatory headline, while Austin legacy metal crew Agony Column – 40 next year – stack up on the Congress Avenue Bridge like the city also does on the Fourth of July, and this summer spectacularly so. DJ Smackola and a dozen other acts pile on. 3pm, $30 advance. – Raoul Hernandez
