Before he co-founded Texas-blues beards ZZ Top, guitarist Billy Gibbons was a psychedelic cat – admired by Jimi Hendrix and already showing some chin carpet – in Houston's Moving Sidewalks, whose '67 single "99th Floor" and '68 LP, Flash, are lysergic-blues cornerstones of the garage revival. The Complete Collection is exactly that: all of Flash – an acid-rock period piece spiked by Gibbons' trippin'-B.B. King flourishes – plus "99th Floor" and other, tough non-LP action such as "Headin Out," a '67 proto-ZZ jam and a fuzz-caked '68 cover of the Beatles' "I Want to Hold Your Hand" that sounds like it's about to melt into "Cheap Sunglasses."

“The A Team”

This debut track from the then-20-year-old British singer-songwriter has a dark story behind it. Sheeran says he culls songwriting inspiration from "viewing other people's situations," which, for the heroine in "The A Team," involves drug addiction and prostitution that began as a teen. Sheeran paints the woman's trials with haunting imagery such as "But lately her face seems/Slowly sinking, wasting/Crumbling like pastries." "I did a gig at a homeless shelter, [and the song] is about one of the women there. It's her story," he said.
