Intermediate/Advanced. Here's the Play-A-Long for all those who have requested a set that utilizes a Guitar Trio instead of the usual Piano Trio as the accompanying instrumentation. The swinging but relaxed sound of the guitar trio brings an intimacy to these songs that will allow you to feel and hear things differently as you play along. A fresh change of pace. With the lyrics printed over the written music, this is an excellent sing-a-long for singers.
