 Since then they have toured together frequently, producing a second album, "Too Few Songs", in 2006, which showcased some of the best songwriting available and a version of the previously unavailable While/Matthews track '36 Miles Away from the Sea'.The album received widespread critical acclaim, as the review in the "Daily Telegraph" put it 'each song remains a showcase for the delicate, complementary powers of expression of two expert vocalists, truly living up to the "more like sisters" description of one admirer, Ralph McTell'.Since then they have produced two more albums, "Too Few Songs" (2016) and "Indigo" (2015).
