It is rare for a band to last for 15 years in any genre, even if it goes through various lineup changes. It is astonishing to keep the same five members throughout a career that has produced several IBMA awards (2008 IBMA Song of the Year winner “Through the Window of a Train” and two tracks from the 2004 Gospel Recorded Performance of the Year winner Wondrous Love are included here) and several SPBGMA awards. Blue Highway celebrates with a collection that sets classics like “Marbletown” alongside newer compositions such as “Cold and Lowdown Lonesome Blues.” The new songs stack up admirably, and prove that, like good wine, some things just get better with time.
