Billy Joel gives us hope. Against today’s pop music landscape, where posturing and production reign, where rhythm and rhyme rule, Billy Joel’s enduring popularity proves that melody still matters. That music is, after all, about music. That, at age 75, pure talent trumps time. And that, even with only three releases in the past 30 years, a Billy Joel-penned pop song can still pack ’em in. Of his generation, there have been few, if any, more successful or accomplished triple threats — singer-songwriter-musician.
