I have been a member of Christ's Church for many years and belonged to many Baptist churches during that time and there is something sadly lacking in many of these churches. Music leadership and fresh styles. There is a great need for small groups of Christians to band together and provide mini concerts for these churches without charging high fees. About once a month a church could greatly benefit from two or three musicians singing and praising God to help breath life into the christian life.
Many small country churches simply lack the talent to support a good music program and many are blessed to just have a piano player and a small choir. Although there is nothing wrong with this approach it can become stale and uninteresting as an act of worship before the Lord. David wrote in Psalm 144:9, "I will sing a new song unto you oh God; on the ten stringed Lyre, I will make music to you."
I believe what David understood was that singing new songs before God showed God that he was willing to author a new song which came from his heart and sing it with great passion. When we as church members sing older songs we often (not always) sing them with less passion because the repetition becomes an automatic response and not something we are thinking about and singing from a renewed passion.
So basically, the Matt and Buck project is this...
Two guys with two acoustic guitars performing cover songs from great Christians like Rich Mullins, Third Day and Chris Tomlin in the context of a helping both believers and unbelievers find God. What better place to sing to the Lord than at the church. We are singing songs which spread the same message of God's forgiveness and grace which has been preached generation upon generation.
