The Estate Project (www.artistswithaids.org), preservers and promoters of works by visual artists living with or lost to AIDS, is adding the aural to their honor roll. To mark the inclusion of composers, John Corigliano, Pulitzer winner for his Symphony No. 2, hosted a May concert at the Guggenheim Museum with jazz pianist Fred Hersh and premieres by Gerald Busby and Martin Henessey, as well as some posthumous pieces by tuneful HIVers.
