As a teenager admiring rock bands and the idea of music as a career, Toby wanted to be part of the action. He was able to get into several recording studios early on and started recording at home. Discovering that his talent wasn't in front of the microphone, he decided the other side of the glass would work just as well. Starting out at a small one-room studio in Hollywood, Clover, the artists and producers on sessions found him to be an excellent engineer. Under the tutelage of mentors, Steve Copper, Tom Dowd, and others, he honed his craft of engineering and mixing.  Among the artists coming into the Clover was Bruce Springsteen, finishing the final mix on his album, Darkness On The Edge Of Town. Toby and Bruce hit it off fairly well and 2 years later Bruce came back looking for a mixer for his next album, The River. Passing a brief audition, Toby spent months mixing to Bruce’s every request.  Following that release, Bruce asked him to record live concerts on that tour.  In between those occasional days on the tour, he was back in the studio with other artists, Bob Dylan and Bette Midler among them.  In 1982, Bruce was back in Clover, this time producing an album for Gary US Bonds and having Toby mix. Once that was finished, Bruce wanted to commence work on his next record with Toby so it was off to New York City and the Power Station recording studio where they began work on Born In The USA.  Subsequently, Toby moved to New York City as his home base and another tour and live recording.  In 1987 Bruce had him set up a studio at his house in New Jersey with enough equipment to cover everything they needed.  That turned into the Tunnel Of Love album, which was basically Bruce playing all instruments, and Toby recording and programming drum patterns with no other participants.  This collaboration and process continued on successfully for another 20 years. During that time Toby was continuing to work with other clients and occasionally at his home in Whitefish Montana. In 2018 they parted ways and Toby worked full-time at his studio, Cabin 6 Recording. There he records everything from narrations, singer/songwriters, rock and country bands, and occasional remotes recording the local Glacier Symphony Orchestra. Always looking for a way to pass on his experience and knowledge to those upcoming in the industry, he speaks at colleges and other schools of audio engineering year-round.

Paul Aubuchon began playing piano at age 5,and by high school (CBC in St. Louis) was absorbed in music to the point of enrolling in every available music class. There he met Bob Horner (ISI) and Casey Hunter (Webster U) and they began performing together as “Strange Case”, enjoying solid college market success and releasing In Eleven Parts. (Thanks, Webster studios!) 

After college, Paul spent 18 months touring the western US as part of a country music foursome. This taste of travel led to a 12 year stint as part of the Department of Defense Professional Entertainment Organization, both as a performer and tour manager. Visiting 43 countries, some multiple times, led to an awareness and respect for fundamental cultural and human differences, along with a lifetime’s worth of laughter, wonder, and crazy adventures. 

After accompanying the Incarnate Word Academy H.S. choir on piano during a performance tour of Ireland, Paul was asked to become IWA’s Director of Music. During his 11 years at IWA, he was responsible for teaching 3 levels of choir, orchestra, piano, guitar, and created My Tunes, an immersive study of post WWII pop music with an emphasis on breakthrough female performers. Paul has enjoyed acting as Musical Director for more than 50 musical productions at local schools and churches, and has contributed piano and keyboard work on several albums covering country, pop, rock, and Christmas genres. 

Throughout this time, Paul continued audio and lighting tech work on shows with Bob Horner at ISI. In 2016 he moved to a full-time position with ISI where, among other things, he oversees developing talent for the future growth of ISI with internship and training programs.

Hi, my name is Obeid Khan and I started out as a guitar player that needed to repair my amps, way before the knowledge base of the internet. I ended up working for one of the largest musical amplifier manufacturers, St Louis Music. At SLM I designed many classic amplifiers for Crate and Ampeg, the original Vintage Club and its variants, Ampeg Diamond Blue reissue amps, the B15 reissue, and the Ampeg SVTDI. Also, I was the designer of the Reason amplifier line, and most recently the new Magnatone line of amps. I always try to connect with the player sonically with my designs, I hope you will find this to be true as you learn more. The amplifier is a tool to make an electric guitar sound. These inherent rules I did not make, but I live and abide by them!
