The conductor from its founding until the end of 2011 was Raimo Henriksson, the grand old man of Finnish big band music, who received the 2003 EMMA Award for his life's work. Since spring 2012, JASO has been led by Ari Jokelainen - a top alto-saxophonist and music teacher.

In concerts in Tartu and Tallinn JASO BB will play music of the legendary composer and arranger Sammy Nestico (6.2.1924-17.1.2021), from differing eras of his career. Nestico started co-operation with The Count Basie Orchestra in 1967. The first results of Nestico`s “creative pen” were recorded in October 1968 on the album "Basie – straight ahead". All 9nine titles of this record, including the main, were composed, arranged and orchestrated by Sammy Nestico. Sammy continued to work for Count until the death of “the Maestro” in 1984. Nestico had also many projects with and connections to major European big bands, such as the BBC Big Band and SWR Big Band in Germany. 

Big Band Tartu 
brings since 1998 together active people with a keen interest in music who, even though they are professionally engaged in a variety of fields from marine biology and landscape design to music-teaching and financial management, have a sincere desire to perform and present relaxing jazz music in Tartu and beyond.

Almost 25 years of making music, the orchestra has given a number of concerts and performed at many festivals in Estonia (the Viljandi Folk Music Festival, Student Jazz, Tabasalu Big Band Fest, Rainbow Jazz, Võsu Viis, Mürtsub Pill and more), Finland (Tampere 2015, Imatra Big Band Festival 2014 and 2022, Turun Taiteiden Yö 2010 and Lahden Jazzitori 2010), Latvia and Lithuania (Vilnius Band 2003 and Trakai Fanfare Week 2009). 2016 we participated in Netherlands, Hoofddorp in Corendon MeerJazz 20th International Big Band Competition and took from there the 3rd place in 1st class (candidates over 200 bands). Big Band Tartu performs at an average of 20-30 concerts, dance evenings and other events each year. For more information on the band and its recordings and history, see http://www.convivo.ee/.

In our 27th season, we have taken to investigate more deeply funk and salsa music, and for this we have invited to help us trumpeter, conductor, arranger and pedagogue Tapio Maunuvaara from the European Capital of Culture Oulu 2026. We will perform world music selected by him, some in his own arrangements. It is very exciting to hear real salsa music, ABBA in funky arrangements, and some Bob Mintzer pieces in between.

Concert Orchestra of Estonian Wind Band Conductor's (VOP)
has been active since 1965, bringing together conductors, instrument teachers and students from all over the republic. It's a project orchestra operating in the form of a seminar, which meets 3–7 times a year in different parts of Estonia (if possible in cooperation with a local collective, foreign lecturer, sometimes also as part of a foreign trip).

Over the years of its operation, over a couple of hundred musicians have participated in the orchestra. VOP was and is a unifier of generations and a carrier of Estonian wind music traditions. At the same time, it is also a special creative laboratory, whether as a premiere performer and evaluator of the repertoire of youth or general song festivals or as a presenter of works by Estonian composers. The main goals of the orchestra are to promote Estonian wind music, disseminate professional information, and prepare joint activities of wind orchestras (song festivals, wind music days, etc.).

The chief conductor of the orchestra is Bert Langeler, a Dutch living and working in Viljandi. Current season the orchestra will be conducted also by Ott Kask, Aigar Kostabi, Daniel Hinno and Karl Abro.

VOP will present a specially prepared program in the style of a big band, to be performed with a wind orchestra.

The big band has had an inspiring international cooperation project thanks to the support of the Saaremaa Rhythm and Improvisation Camp - on 24.01. 2020, a concert was held at the Tallinn Methodist Church under the guidance and participation of the US saxophonist and pedagogue Ned Ferm. The orchestra is guided by Ott Kask and Ivo Jürisson.

Tartu Sax Choir 
was born on the initiative of maestro Lembit Saarsalu and with the modest help of the Salvador Sax Quartet in January 2003, when on the occasion of Lembit Saarsalu's 55th birthday, all the halls of the Estonian Concert were toured. The choir is trying to deepen the passion for playing the saxophone, especially among young players, so that even after 120 years, playing the saxophone will appeal to young people as an enjoyable alternative. As a result of the work done, several nice neck-wearing saxophone ensembles have started in Tartu, and listeners and players have been infected with enthusiasm, both in their home country of Estonia and behind the track.
