First solo album since 2016: Expectations for The Romantic are likely to be high, because Bruno Mars hasn't released a solo album in ten years. 24K Magic (2016) is his last solo work, followed by collaborations: in single form as a feature with Lady Gaga, Rosé or Cardi B; and in album form: An Evening With Silk Sonic by Bruno Mars and Anderson .Paak proved to be a successful album that paid homage to funk, R&B and soul from the 70s and took home four Grammys.
