An Assistant Professor at the University of Colorado, Denver, Dr. Erin Hackel received her Bachelor’s in Vocal Performance from James Madison University, a Master’s in Opera from Binghamton University and a Doctorate in Voice Performance and Pedagogy at the University of Colorado, Boulder.

Dr. Hackel’s award winning a cappella groups, MIX and Lark have traveled across the United States and Europe competing and performing. Both groups have been BOSS and SOJAM champions, recipients of multiple performance awards, and have won multiple Contemporary A cappella Recording awards (CARAS). MIX and Lark have been praised for their innovation and professionalism and have been singled out for their boundary changing work in collegiate a cappella. Dr. Hackel’s ensembles have collaborated with the Swingle Singers, headlined the National A cappella Convention, and won the Most Innovative Group award at the Aarhus Vocal Festival in Aarhus, Denmark.
The lives of female composers and performers are central to Dr. Hackel’s research and publication history.

"Martin Katz must surely be considered the dean of collaborative pianists," said the Los Angeles Times, and Musical America magazine created an award expressly for him: Accompanist of the Year. One of the world's busiest collaborators, he has been in constant demand by the most celebrated vocal soloists for more than four decades. He has appeared and recorded regularly with Marilyn Horne, Frederica von Stade, David Daniels, Karita Mattila, Jose Carreras, Cecilia Bartoli, Kiri Te Kanawa, Kathleen Battle, Piotr Beczala, Joseph Calleja to name just a few.
A native of Los Angeles, Mr. Katz attended the University of Southern California and studied the specialized field of accompanying with its pioneer teacher, Gwendolyn Koldofsky. While yet a student, he was given the unique opportunity of accompanying the classes and lessons of such luminaries as Lotte Lehmann, Jascha Heifetz, Pierre Bernac, and Gregor Piatigorsky. He has partnered several of his soloists on the podium for orchestras of the B.B.C., Houston, Washington, D.C., Tokyo, New Haven and Miami. He also conducted staged productions for the University of Michigan's Opera Theatre, the Music Academy of the West, and San Francisco Opera’s prestigious Merola program.

Finally, the professional profile of Martin Katz is completed with his commitment to teaching. For three decades, the University of Michigan has been his home, where he has been happy to chair the School of Music's program in collaborative piano, and play an active part in operatic productions. He has been a pivotal figure in the training of countless young artists, both singers and pianists, who are now working all over the world. In addition to his work at his home school, he is a regular guest teacher at Helsinki's Sibelius Academy, Songfest, Chicago College of Performing Arts, Canadian Operatic Arts Academy, and the New National Theatre of Tokyo.
Mr. Katz’s comprehensive guide for accompanists, “The Complete Collaborator,” published by Oxford Press, is widely seen as the standard for textbooks on this subject.
