It was a sign of the times when the Downtown Davenport Partnership announced last month that it would replace the River Roots Live outdoor music festival – after a 12-year run – with a multi-venue indoor festival called Alternating Currents.

Consider what’s happened over the past two years. The Mississippi Valley Blues Festival was canceled in 2015 because of financial difficulties at its parent organization. The motorcycle-themed Rally on the River, a fixture on the riverfront for more than two decades, didn’t return in 2016.

All of these things reflect a simple reality: Outdoor festivals are expensive to put on, period, and the cost is much higher with headliner acts to drive attendance. Such events represent a serious financial gamble: Just the chance of rain on one day can depress turnout enough to put a festival in the red, and Mississippi River flooding can force an expensive change of venue.

But let’s not mourn River Roots Live too much. If its death underlines the inherent risk of outdoor musical festivals, its replacement shows just how vibrant the Quad Cities music scene has become.

If you want to know the secret of Sister Wife’s Trap House, you probably shouldn’t ask the Quad Cities-based duo of guitarist/vocalist Samuel Carothers and drummer Matthew Ashegiri. They work largely by instinct, and on this album those instincts are – far more often than not – startlingly spot-on.

Not yet two years old, the band has worked with producers – on a single for Milwaukee’s Honeytone Records and an EP – but chose to go it alone for Trap House, the debut album Carothers and Ashegiri self-released last week.

“I am embarrassed to be here,” sings Wild Pink singer, guitarist, and songwriter John Ross on “I Used to Be Small.” The “here,” in this case, is the United States.

On the New York-based indie-rock band’s self-titled debut album, Ross explores getting older through the people and places around him. The past is at the forefront, with Ross recalling looking through the window at the Hudson Valley, being told that “if you never stop moving, then you’ll never feel bad” in “Broke on,” a journey through memory. He sings about being a passenger in a parent’s car, riding bikes, “hearing about the war, and knowing it’s not yours.” The listener gets access to moments that shaped whom he became.

When Owen Ashworth dissolved his solo project Casiotone for the Painfully Alone after more than 10 years, he set out to start anew.

“I liked the challenge of starting over and just writing a whole new set of songs and seeing what a blank slate would feel like,” he said in a recent phone interview.
