When the complementary skills and songwriting rise to the level of collaborators Mark Olson and Gary Louris, a minimal presentation is just fine. Two voices, two acoustic guitars, some sparse, pulse-keeping percussion by a third party - that was it for the duo's sold-out show at the Sellersville Theater 1894 on Monday night. Plenty fine.
Assisted by Norwegian native Ingunn Ringvold on (mostly) djembe, Olson and Louris were frequently enthralling through 21 songs. The dozen tunes presented from their new album, Ready for the Flood, held up sturdily against time-tested fan faves. Those included the unexpected encore "Clouds" and the concert-closing "Blue" from the pair's 1985-95 heyday as cowriting front men for the acclaimed Minneapolis "alt-country" pop-rock-roots band the Jayhawks. (The band never managed the same magic after Olson's 1995 departure.)
