The Welsh-born singer Donna Lewis is one of those rare artists whose immense success on the pop radio charts disguises an exceptional and serious musicianship and breadth of repertoire. Lewis’ new album,Brand New Day, reveals the range of her artistry, and may surprise listeners who know her only for herpop hits “I Love You Always Forever,”“At The Beginning,” “I Could Be The One” and “Love Him.” Produced and arranged by Lewis’ longtime friend DavidTorn, the genre-busting composer and producer, Brand New Day is an intoxicating set of jazz-inflected covers and Lewis originals in which she is joined by the eminent progressive jazz musicians Ethan Iverson (piano), Reid Anderson (bass) and Dave King (drums).
