The Fifth House Ensemble of Chicago chamber-music group aims for the stratosphere with Excelsior, its adventurous debut album on Cedille Records. The title refers to an experimental, extreme-altitude U.S. Air Force project of the Cold War era. Excelsior presents world-premiere recordings of works by Caleb Burhans, recipient of commissions from Lincoln Center, Carnegie Hall and the Library of Congress; prolific, award-winning composer Alex Shapiro; and Jesse Limbacher, winner of the ASCAP Morton Gould Young Composer Award. The disc also includes a work by Mason Bates, Chicago Symphony Orchestra composer-in-residence. Commissioned by Fifth House Ensemble, Burhans’ 30-minute title track depicts Captain Joseph W. Kittinger’s 1960 record-setting free fall and parachute landing from a height of more than 19 miles above the earth. Excelsior transports listeners through a seamless, ethereal blend of acoustic and electric instruments and voice, propelled by suspenseful, repeating motifs.
