Two of Sacramento’s most prominent musicians are joining forces for a weekly songwriter’s showcase at Cafe Colonial, a new-ish all-ages venue located next to the Colonial Theatre on Stockton Boulevard. The Tune-Up started at Kevin Seconds’ long-defunct True Love Coffeehouse many years ago and has been resurrected a number of times since at various venues. This time around, Seconds will co-host with David Houston weekly on Wednesdays at 8 p.m. starting on Dec. 18, 2013 (note: there will be no show the following week on Christmas, obviously). There will be no cover charge to attend the Tune-Up, so if you can, bring a little cash for food, drinks and if you feel so inclined to tip the songwriters. Each week, Seconds and Houston will host, alongside special guests like Tom Hutchison of the Knockoffs (Dec. 18), Dr. Velocity (Jan. 1, 2014), Warren Bishop (Jan. 8, 2014), Autumn Sky (Jan. 15, 2014) and Jackson Griffith (Jan. 22, 2014).
