Deb Hunseder and Steph Callahan met in 1989 and had their first gig two weeks later. The harmonies were magic. From the first note, they knew they had something that could not be matched. Since 1989 the duo has opened for national acts including John Mayer, India.Irie, Joan Osborne, Tabithas Secret (now Matchbox 20), Sister Hazel, Crosby, Stills, and Nash, Joan Bias, Cheryl Wheeler, Wynona Judd, Patrice Pike, Sarah Bettens, Melissa Ferrick, and Koko Taylor.
They've also performed their stirring acapella rendition of the national anthem for the Atlanta Braves, Tampa Rays and the Tampa Bay Buccaneers.
Halcyon has built an iron clad fan base by touring the US and abroad. They've played many main stage Pride events, Olivia cruises and festivals including Atlanta, Chicago, Seattle, Portland, Denver, Alaska, York, England and tour heavily in the southeastern US.
With nineteen years of experience, and seven CDs between them in the bag, this duo is a finely tuned personable act. They are capable of touring as a duo, or as a band.
