Almost six years ago, Peter Margasak wrote that if the growth the Chamber Strings had shown between their 1997 debut, Gospel Morning, and its 2001 follow-up, Month of Sundays, was any indication, “their third one should be an instant classic.” We’re still waiting to see if they prove him right. After playing his final show with the band on Thanksgiving Day in 2001, singer and songwriter Kevin Junior fought a long bout with depression and drug addiction–he didn’t start to get the upper hand till 2004, after a rather rocky tour of Europe with frequent collaborator and Swell Maps veteran Nikki Sudden (who passed away last year). Junior’s been trying to pull off this reunion for a long time and already has a couple albums’ worth of material ready to go. A few of the new songs will make it into tonight’s set, which he says will otherwise consist of the band’s “greatest hits.” For more, see this week’s feature in Section 1.
