Jonathan speaking: Someone asked me to define the "Testament (the band)" formerly "Iplan Christian Rock" sound awhile back.... It was the first time anyone had ever asked me "that" question, and it had me stumped for awhile. That said, after giving the question a great deal of thought, I responded, "If you can picture KISS and Joan Jett meeting Third Day in an abandoned warehouse, for a knife fight you're on the right track." Testament (the band) is mostly an electric guitar driven machine, featuring powerful vocals, and catchy lyrics . The songs are typically riff based, positive, and uplifting.
