Performing a Moeller Nights concert on June 27, the Heligoats – what NPR called “a strange name for a guy strumming a guitar, but oddly befitting someone who stuffs his songs with so many sideways ideas and observations” – delivers acoustic indie rock courtesy of singer/songwriter Chris Otepka, whom NPR declared “writes songs that are brainy in the best way: clever without straining for cuteness, wry but never smug.”

Praised by Whatsup Magazine for music that delivers “the lyrics as spells, the melodies as enchantment, the rhythms as the primal beatings of the heart,” the folk artists of Joseph play a Moeller Nights concert at Maquoketa's Codfish Hollow Barn on June 27, sharing what the magazine lauded as “a harmonic alchemical transmutation of word and music into shimmering epiphanies of transcendent meaning.”

Performing in support of their sophomore album Arms of a Dream, a spring release that Ghetto Blaster magazine deemed the band's “most vivid and transformative music to date,” the Canadian musicians of Reuben & the Dark play a Moeller Nights concert on June 17, their folk-rock stylings leading American Songwriter to dub the group “Bright Eyes meets Mumford & Sons.”

With Broadway World calling the performers' live show “an awe-inspiring experience” in which the phrase “'must-see' doesn't really cover it,” the global phenomenon Celtic Woman brings its “Homecoming Live” tour to Davenport's Adler Theatre on June 12, demonstrating why the Irish musicians' international appearances have been continual sell-outs, and why they have thus far sold in excess of 10 million albums worldwide.
