There's a backstory here. ''Heart of Gold" was filmed over two nights in August of 2005, a few months after the 59-year-old Young went into surgery to repair a potentially fatal brain aneurysm, not long after his father died, and shortly before he released ''Prairie Wind," an album that aches with resilience and loss. The director was Jonathan Demme, who 22 years ago made what many consider the greatest concert movie ever: ''Stop Making Sense," featuring Talking Heads at the height of its powers.
That film remains an electrifying testament to pop music as a communal creative act. ''Heart of Gold" -- filmed in much the same manner, with pristine sound and a notable lack of audience shots -- is a deeper and infinitely more touching piece of work. Even when Young is surrounded by an onstage crowd of musicians, old friends all, he seems alone. The songs have been chosen from across his catalog to address matters of death, aging, remembrance.
And yet the thing glows. As someone who has always valued the thrash-Neil of Crazy Horse albums like ''Ragged Glory" and ''On the Beach" over the hippie-Neil of ''Harvest," I went in expecting, at worst, a toothless boomer nostalgia trip. Young's always been the trickster of the singer-songwriter movement, though: Even at his most overreaching (the recent ''Greendale") or bizarrely wayward (the vocorder album, the rockabilly album), he has held on to the anarchic pulse of rock 'n' roll -- to the idea that ''it's better to burn out than fade away." This gives his quietest songs a toughness that pays off here.
