Two locally produced documentaries about St. Louis music are premiering tonight as part of SLIFF. The Pride of St. Louis chronicles the rise and fall of Mama's Pride, in the words of brothers Danny and Pat Liston, while Old Dog, New Trick throws the spotlight on Steve Scorfina, a founding member of REO Speedwagon and member of Pavlov's Dog. The 7 p.m. Tivoli screening will be followed at 9:30 p.m. by a show at the Duck Room with Danny Liston and the Scorfina band. Tickets are $10 to the movies, $10 to the concert, or $18 for both, available at the Tivoli's box office. Christian Schaeffer reviewed both movies this week in the RFT; view a trailer for Old Dog, New Trick below.
