Dear Catastrophe Waitress collects Belle and Sebastian’s greatest strengths: sugary, impossible-to-forget melodies and jangly indie pop. The title track offers up a jaunty acoustic strum pitted against orchestral flourishes, and “Stay Loose” harks back to ‘60s-era English dance floors, combining classic pop and New Wave sounds. “Piazza, New York Catcher” is a sweet, folky love song stripped to just acoustic guitar and Stuart Murdoch’s gentle vocals, and “Lord Anthony” feels like classic, poignant B&S, with a gentle melody and fluttering strings.
