Have you discovered Grapevine Magazine? In my mind, it is the absolute best resource to discovering the latest from Catholic Contemporary musicians, liturgical and entertainment-oriented. Run by Susan Bailey, there are musician profiles, latest events, and music reviews. The resulting magazine is quite attractive in print, and the articles draw attention to this otherwise "blind-spot" in Christian music.
Not to be outdone with print, Susan Bailey has been promoting the Grapevine News Minute (actually, about fifteen minutes), a weekly podcast which allows you to dig deeper in these stories, and get to hear songs live.
Susan Bailey, along with George Leite (of Catholic Jukebox/Catholic Rockers/Catholic PraiseCast fame) presented an informative session at the Catholic Faith & Media Conference at Franciscan U of Steubenville, earlier this month. They even got a few good blurbs about Top Catholic Songs in... Thanks So Much!! (Check out their presentation on Grapevine's main page).
