Alison BrookAlison Brook is first and foremost committed to the Gospel. Her wide range and eclectic musical taste contribute to her very unique folk/pop guitar-based sound. Her melodies are sweet and her lyrics are loaded. Alison's debut album, No Words, captures the singer’s energetic soprano without compromising its elegance. On this musical journey, she sings her way through struggle and victory alike, always returning to the love that is beyond even the album’s poetic words. Alison’s sophomore project was quickly conceived after No Words as she chronicled her life experiences through song. When her Kickstarter campaign exceeded its goal, she knew others anticipated the album as much as she did. Working with Philadelphia-based Delon Lawrence to record the album’s eleven tracks, she went for an “urban-folk” sound, providing cameos for spoken word artist Lee G. Due out in early 2014, the album promises to showcase the best of Alison’s pen and voice.

Currently, he is the pastor of the Epic Church in Chicago. Epic focuses on discipleship with senior youth and young adults while engaging them in creative ways with the story of the Gospel. For Andres, worship is a great passion because he believes that it is an important gateway to help new believers to connect with God and with our church.

Scott KabelScott Kabel enjoys telling stories with songs. And he prefers that his songs spark conversation. Scott has been writing songs since elementary school; they are  clear waypoints in his journey of development, not only as a musician, but as a Christian learning to grapple with his own humanity and purpose. He offers conversational melodies and folk and finger-style guitar to dialog with the listener about topics like the human condition, value, vulnerability, love, sacrifice, and hope in Christ. Scott only hopes that his songs and presentation will challenge the listener to be honest with themselves and to look to Jesus to overcome.
