This still-nameless ballad (fans are calling it "Home") sounds like Arcade Fire reborn as a string band. Cut live in a radio station, it's a slow-builder that threatens to explode but never does. It may be a taste of Mums' upcoming LP; either way, its sad hunger feels universal.

“Is It True”

As the British Invasion reached its peak in 1964, Brenda Lee went from Nashville to London to record one of her hardest-rocking hits, her perky vocal backed by a stuttering, squalling guitar. That guitar was played by session musician Jimmy Page, yet to skyrocket to fame with first the Yardbirds and then Led Zeppelin. "She said to me, 'I've come here to make a record with the British sound,'" remembered producer Mickie Most. "She felt she wouldn't get the same sound in Nashville because they're only just catching up on the British beat group sound of about six months ago."
