Neil Young hasn't dipped much into the old-time kiddie songs from this year's Americana in his latest Crazy Horse shows. Instead, he's using this tour to blow minds with intense new tunes that come on like pieces of an in-progress autobiographical song cycle. "Twisted Road" is an acoustic beauty; Young reminisces about hearing Dylan and the Dead on the radio. But "Walk Like a Giant" (also presumably from Young's next album, due this fall) is the mind-blower: an epic feedback monster, stretching to the 20-minute mark. It tackles familiar Young themes – the passing of time, the death of the hippie dream – with furious guitar noise and a whistle-along chorus. "Walk Like a Giant" is a fearsome sound: The old man takes a look at his life, and gets righteously pissed off at what he sees.

“The Everchanging Spectrum of a Lie”

The opener off the Welsh group’s The Big Roar album was an epic one, but the band was worried that track had polarized fans. “The first song is eight minutes long,” Rhydian Dafydd, the Joy Formidable bassist, said. “If you did that in the Seventies people would be, ‘Whatever.’ You do it now, people think, ‘Holy s---!’ Some people think it’s the f---ing greatest track on the entire album, and some people think it’s f---ing boring. It’s that element of needing to challenge people.” The band concluded through the song’s lyrics that love was the “everchanging spectrum of a lie.”
