The backdrop depicted a large bear embracing the state of California, a nice metaphor for the music emanating just a few yards closer.

For 75 minutes Sunday night at the Granada in Lawrence, indie pop duo Best Coast showcased the many of the Golden State’s finest musical attributes – girl groups, surf guitars and bubbly pop melodies about summer and love.

The band makes a strong case for being their home state’s finest musical ambassadors since the Beach Boys. Opening number “The Only Place,” which also opens and titles their recently released sophomore album, set the stage. “We’ve got the ocean/got the babes/got the sun/got the waves,” Beth Cosentino sang over jangly guitars. \

“So leave your cold behind/we’re gonna make it to the beach on time.”

The sun is usually out in Cosentino’s musical world, but not always in her heart. Her lyrics are direct and confessional, often reading like diary entries about lost, misplaced or inconvenient love. The band’s 2010 debut had a lo-fi feel that added to the intimacy of her words. Onstage, the twosome of Cosentino and guitarist Bobb Bruno are touring with a bass player for the first time. Combined with a new drummer, they finally had a live rhythm section that adds muscle and potency to the music.

The bass added depth to the sound and gave Bruno more freedom on his guitar. The drumming enhanced the sense of desperation in “Why I Cry” and gave urgency to “Angsty.”

For 75 minutes, the Cosentino’s pop memoirs of longing came tumbling one after another, comprising nearly all of “The Only Place,” more than half of their debut “Crazy For You” and a handful of singles.

The whole room was dancing for the bouncy pairing of “Let’s Go Home” and “Our Deal,” but the slower material went over just as well thanks to Cosentino’s captivating voice. An emotional cover of Fleetwood Mac’s “Storms” hinted at the direction Cosentino’s songwriting may be headed. It covered the same romantic terrain, but boasted more lyrical maturity and depth.

Cosentino and Bruno clearly aren’t tired of playing “Boyfriend,” their breakout hit. Cosentino threw herself into the delivery, nearly growling the words “how I want him.” The pair were all smiles throughout the one-two of early singles “When I’m With You” and “Boyfriend” that ended the night.

Just as Best Coast benefited away from the blistering sun and heat that capsized their mid-day slot at Kanrocksas last summer, opener Jeff the Brotherhood was better suited for the Granada than the cavernous Midland Theater, where they opened for the Kills last winter.

The sibling duo from Nashville’s half-hour set was driven by guitarist Jake Orrall’s 3-string, hybrid guitar. The axe featured a Gibson body and bass neck and was filtered, flanged and phased about every way imaginable, often sounding like Black Sabbath’s meeting with Swamp Thing. The high point of their set was “I’m a Freak,” a straight-up, classic rock guitar jam in the vein of “Stranglehold.”
