The ICA celebrated its 25th Anniversary at the 1998 ClarinetFest® at Ohio State University, a festival that was hosted by James Pyne. During this festival, the ICA set a new Guinness Record, with 280 clarinetists performing “When the Saints Go Marching In” on stage with the Columbus Symphony during the “Picnic with the Pops” concert.
The association also reached the milestone of 4,000 members in 1998.
