Our Founding Father

RCJO was started at Inver Hills Community College
 in 1980 by Dr. Herminio Diaz.

The group was founded by Dr. Herminio Diaz, music director. The idea was to give talented, Twin Cities area musicians an opportunity to learn playing "Big Band" jazz styles. The band recently changed its name from Inver Hills Community College Jazz Band to RCJO, and is now self managed by its own members as a non profit organization.


RCJO focuses on playing a large variety of jazz tunes including Bassie, Dorsey, Ellington, Foster, Miller, Nestico, and many, many more. RCJO plays everything from hot, up-tempo charts, sensitively treated ballads, show tunes, classic dance tunes and modern titles.

RCJO has performed around the Midwest. The Band has hosted several jazz festivals as well as participated in jazz festivals hosted by the University of Minnesota, University of Wisconsin - Eau Claire, and KBEM jazz radio (now known as Jazz 88 FM - tune to 88.5 FM in the Twin cities) .

Education has always been a goal of our group with joint concerts at High Schools such as Henry Sibley, South Saint Paul, Woodbury, and Hastings.

Sharing our music with other musicians has been especially enjoyable with the Roseville Big Band, University of Wisconsin - River Falls Jazz Band, and Hamline University Jazz Band, and North Hennepin Community College Jazz Band. The Group has been a regular at O'Gara's in St. Paul since 1994. (Note: The accompanying photo is of the 1993 group at Como Lake pavilion.)
