The public will have the opportunity to horn in on a number of events planned as part of the International Trumpet Guild Conference at the UI from June 15 through 18. Guild members - including musicians, teachers and scholars from around the world - meet annually at a different location to share information and participate in performances and competitions, according to this year's host, UI music professor Michael Ewald. All events open to the public will be held in various locations at the Krannert Center for the Performing Arts. See the Calendar for details. Some concerts - including those by military bands - are free. Beginning Monday, tickets for various other conference events at Krannert Center will be available to the public. Those events each have a $10 admission price.
