"JonasJonasJonas Jonaaaas!" was the chant of choice for kids everywhere in 2008. Now that the alpha boy band of the moment have delivered a rocking third album, expect the cheers to graduate to their college-age brothers and sisters - even their Big Star-weaned parents. This is a generation-gap closer if there ever was one. The boys quite obviously love the Beatles, and their snappy garage pop - all fuzzed-up chords and candy floss choruses - succeeds on such sunny goodwill. Lead single Burnin' Up is a Prince-worthy pool-party jam - and one of the year's great lust-pop gems at that. There's expert balladeering on Lovebug, and it's business as usual elsewhere with tearing guitar solos and yelps of "ah-yeah". The rocker-coiffed brothers even manage some vulnerability along the way. Shelf is a mid-tempo, yearning love song; the title track comes replete with plaintive vocals, piano and strings that would induce any self-respecting Avril Lavigne Jr to cry away her keenly-applied mascara. But this is more than just sweet sneer. It's as confident as any rock record released this past year - perfectly poised between banging bubblegum pop and meticulous mature craft. Rest assured that a spate of dads will be furtively burning copies of their daughters' CDs to play in the car on their way to work.
