Born in Risskov, Denmark in 1978, Bro played trumpet in his youth and was first exposed to jazz through his father's big-band and jazz record collection. Around age 12, Bro also started playing guitar, a passion that overtook trumpet and led to stints studying music at such institutions as Denmark's Rhythmic Conservatory, the Berklee College of Music in Boston, and the New School for Jazz and Contemporary Music in New York. Although he never secured a degree, his adept approach to improvisation and group interplay caught the ear of local N.Y.C. musicians including Paul Motian, who hired him to play with his Electric Bebop Band and featured him on the 2004 album Garden of Eden.
Since the mid-2000s, Bro has worked with a bevy of artists including Lee Konitz, Bill Frisell, Paul Bley, Chris Cheek, Ben Street, Mark Turner, Chris Speed, David Virelles, and others. As a leader, Bro has released a steady stream of albums, beginning with Daydreamer (2003) on Loveland. More efforts followed on the label, including Pearl River (2007), The Stars Are All New Songs (2008), Balladeering (2009), Bro/Knak (2011), and December Song (2013). Bro made his ECM debut in 2015 with Gefion, which showcased his trio with bassist Thomas Morgan and drummer Jon Christensen. Streams followed a year later, with Joey Baron in the drummer's chair. In 2018 he delivered the deeply lyrical Returnings, featuring longtime drummer Christensen, bassist Thomas Morgan, and Scandinavian jazz giant trumpeter Palle Mikkelborg. In October, ECM issued Bay of Rainbows, featuring the Streams trio. The release captured the band live at New York's Jazz Standard in 2017, playing a selection of tunes from Bro's catalog. In early 2021, he issued his fifth outing for ECM. Entitled Uma Elmo, his trio on the date included Norwegian trumpeter Arve Henriksen and Spanish drummer Jorge Rossy, musicians he admired but hadn't recorded with before. Composed of eight original tunes, it was produced by Manfred Eicher. He then paired with saxophonist Joe Lovano for 2022's Once Around the Room: A Tribute to Paul Motian. ~ Matt Collar, Rovi
