Band Bios
Jazz Spectrum
BOB ZAUN, piano, arranger...At age 14 he quit piano lessons after four painful years.  At age 16 he was introduced to jazz...Ella, Oscar,
Sarah, Kenton, Basie, Ellington, The Four Freshman, and The HiLo's.  As junior in college, he met a real piano player.  Bob asked if he played in a
group.  "No, but I'd like to.  What do you play?," he asked.  Without a hitch Bob replied, "bass."  Bob figured that the notes were so low they didn't
matter, he just had to look good! That evening he called his father and said that he decided to minor in music and needed to play a second
instrument.  His dad said, "I didn't know you had a first!"  And so birth was given to his first group, The Bob Fiasco Trio.  Eventually Bob became an
accomplished bass player and began playing piano in keys other than C.  His writes all the vocal and instrumental arrangements, plus writes
vocalese lyrics in the style of Jon Hendricks.   He is married with two children and two grandchildren.  Daughter, Stacy, sings the alto part and son,
Greg has perfect pitch and transcribes big band arrangements for Bob's vocalese lyrics. After graduating from Valpoaraiso University, Bob spent
four years in the US Air Force gaining the rank of Captain.  He pursued a career in real estate, building a 12 office company in the Northwest
Suburbs of Chicago.  After 15 years in real estate he became a mortgage banker with Margaretten & Co.   After 15 years and various acquisitions,
he retired from Chase Home Mortgage in 2000 as a Regional Manger.  In 2016 he was inducted into his high school's Hall of Fame.
JOHN EIFERT, drums...Formal lessons were started at age 4 and he played his first professional gig at age 11.  John played 5 summers at
Marriott's Great America and was section leader for the nationally acclaimed John Phillip Sousa Honor Band performing in Washington, DC.  At the
University of Illinois he successfully crammed four years into six, majoring in percussion and music education.  He was captain of the drum line and
President of the symphonic band his senior year.  It was there he met Stacy, Bob's daughter, as they marched together in the snare line of the
Marching Illini.   Bob became friends with John and, upon graduation, hired him as a mortgage loan officer.  Truth be known, Jazz Spectrum then
was an instrumental quartet  always in need of a drummer.  Bob figured he'd kill two birds with one stone.  Little did he know he'd also get a
son-in-law in the bargain!  Stacy & John have two children, both talented musicians.  
LARRY BOISEN, saxes, flute, clarinet, harmonica, oboe...We met Larry in 2001 when he was in the audience at a Jazz
Spectrum concert.  He became a permanent member of Jazz Spectrum in 2004.  Larry and Bob have collaborated on various projects including
writing a commercial for WRLR-FM which Jazz Spectrum recorded.  Larry has backed numerous popular performers such as Joey Lewis, Jerry
Vale, The Harmonicats, and Leslie Uggums.  He has toured with Les and Larry Elgart, Ralph Marterie and Ralph Flanagan.  He is a playwright,
composer,  lyricist, author and poet....and fluent in 9 languages!   He composed the title tune for Jazz Spectrum's CD,
It's Christmas. Larry
graduated from Northeastern University with a major in English and French.  Prior to retiring after 30 years with the US Post Office, he served 3
years in the US Army and taught English and the Arts in the inner city of Chicago.   See: his web site: www.recitalmusicplus.com
BILL ZIELINSKI, bass...In February 2004 Jazz Spectrum was recording their 2nd CD, "It's Christmas."  We needed an acoustic bass for
one of the numbers and Bill was recommended.  Our longstanding bass player, Tom Sievers was trying to retire.  He was happy to surrender
his spot to Bill.  While we were sad to lose Tom, Bill was a happy addition to Jazz Spectrum.   Bill is married and has one son who is a very
talented trumpet player studying for his Master's Degree at Purdue University.  Every kid has got to envy Bill's dream job...developing video
games!  Currently he is working on in flight internet service.
DENNIS SULLIVAN, trumpet....Dennis was Stacy's band director at Mundelein High School in the early 1980's.  He and Bob became
good friends and he played a few gigs with Jazz Spectrum when it was an instrumental ensemble.  He currently is a private trumpet teacher
at three local high schools having over 75 students.  We are so happy to finally have him as a full time member of Jazz Spectrum
DAVE KUBLANK, saxes, flute...it was the summer of 1982 when Dave Kublank, a Libertyville High School senior, was prodded by his
father to sign up for a jazz improv class Bob Zaun was teaching at the Adler Center in Libertyville.  His dad was concerned that his son wasn't
motivated to practice.   Dave worked hard that summer and found joy in practicing jazz licks and incorporating them into his solos.  He returned to
play lead tenor and principal soloist in Libertyville's award winning jazz band.  He went on to earn a performance degree at Northern Illinois
University and was chosen for the Disney All American College Band.  He also played in Marriott's Great America band.  Dave is a "first-call"
tenor player for many big bands in Chicago.  He and Bob maintained contact over the years, playing an occasional gig together.  Who would have
predicted that that kid who hated to practice would become such an accomplished artist and be an integral part of Jazz Spectrum.
   LARRY BOISEN EMERITUS MUSICIAN WITH JAZZ SPECTRUM
Larry moved and retired from playing full time with Jazz Spectrum in 2017 after 13 years of service.   
We will miss his playing but we still benefit from his creative writing.  Here is his biography.
