The pair is actually preparing to celebrate their twentieth year together as Over The Rhine.

The duo will mark the occasion with a five part tour, the first leg of which kicks off November 7 at Guilford College in Greensboro, N.C., and will hit Athens, Ga.; Charlotte, N.C.; and Madison, Wis.

The second run of shows covers the West Coast, launching with a pair of shows November 29-30 at The Triple Door in Seattle and moving on to Portland, Ore., Klamath Falls, Ore.; San Francisco and Los Angeles.

Part three of the anniversary trek will see Over The Rhine playing shows in Louisville, K.Y. on December 11 and Chicago on December 12.

The journey will culminate with a trio of shows in Cincinnati. A December 19 show at the Taft Theatre will cover music from the band’s first decade, with a December 20 show at the same venue featuring tunes from the second.

Finally, Bergquist and Detweiler will throw an afternoon soiree at the city’s St. Elizabeth’s Cathedral December 21, featuring wine, festive food, conversation and a special acoustic performance.

And how does the couple feel about two decades as Over The Rhine? A little overwhelmed.

“Almost 20 years, it’s just sort of hard to take in,” Detweiler said on the band’s web site. “There are days when we feel utterly blessed and charmed.

“That this labor of love could continue for 20 years, that our audiences still continue to grow, that this music continues to get spread around by people who are often in the process of becoming life-long friends – it all smacks of the miraculous.”
