Rock In Harmony is part of the Sing In The Barbershop Quartet series which is a great collection that allows men to sing four-part a cappella harmony with a professionally recorded barbershop quartet.
The books include TTBB parts and the CDs feature full performances. Just turn on the CD, open the book, pick your part, and sing along!
