The 1976 rock romance A Star Is Born reflects pop’s hectic mid-’70s landscape through two very different stars. The velvet-voiced Streisand flaunts her disco-diva side on the sinewy “Queen Bee” and the roller-rink-ready “I Believe in Love”, and she turns the delicate Paul Williams composition “Evergreen” into an emotional wallop. The folk-rooted Kristofferson, meanwhile, amps up his growl on the bluesy rocker “Hellacious Acres”. Both take on “Watch Closely Now” with gusto, their contrasting approaches equally suiting the commanding rave-up’s charms.
