It is a challenge to create eleven songs on demand, which is why so many albums consisting entirely of originals are less than compelling. The success rate is high in A Sense Of Wonder, a compact disc of songs written by the veteran Australian tenor saxophonist Laurie Lewis and his lyricist wife Alwyn. Young Heather Stewart sings the songs with a sweet innocence. She handles lyrics well and has good intonation, not an epidemic among vocalists. The jewel of the collection is “Don’t Ask.†I am also taken with the regretful “Rather Than Love†and the title song. Lewis, pianist Mark Fitzgibbon and guitarist Doug de Vries have relaxed solos throughout.
