Originally from New Orleans, Louisiana, Jasen Weaver is one of the most in demand bassists in his hometown and abroad. Under the tutelage of world-renowned musicians such as Donald Harrison and Jason Marsalis, Weaver has become a respected component of the New Orleans jazz community. In June 2021, he obtained his master's degree in jazz performance from the Royal Conservatory of Brussels as a recipient of the VLUHR Master Mind Scholarship.

A graduate of the prestigious New Orleans Center for Creative Arts (NOCCA) as well as the University of New Orleans, Jasen was positioned to be an impact player in the music scene from a very young age. While in high school he was also a member of the Tipitina's Internship Program led by the great Donald Harrison, whose band he joined years later. Aside from being an active performer, Jasen also gives back to the music community by teaching. He was a student teacher at the Don Jamison Heritage School of Music while in college and is currently a faculty member at the Sanaa Music Workshop.

Jasen has toured in Europe, Australia, South Africa, Honduras, Japan and many cities in the United States. He has played legendary venues such as Yoshi's (Oakland, CA), The Jazz Showcase (Chicago,IL), The Apollo Theatre (New York, NY), Ronnie Scott's (London) and Duc De Lombards (Paris). He also has made a name for himself as a recording artist having appeared on albums by Adonis, Rose, Dee Dee Bridgewater, Dr. John, Jason Marsalis, Joe Dyson, The New Orleans Jazz Orchestra, The Session and many more.

As a bandleader, Jasen released his debut album, "The Voscoville" in March 2018 and made his first appearance at the world famous New Orleans Jazz and Heritage Festival that same year. Weaver's band also held the regular slot on Saturday nights at Bacchanal Wine from 2012-2019. Sammy Stein, of Something Else! reviews, may have summed it up best: "Jasen has the authority and privilege to surround himself with talented and also serious musicians. You can hear Monk, maybe Shorter and definitely NOLA in these tracks. More than that, you hear the heart of a young jazz musician who, if this is his first release of his own compositions and arrangements, we are definitely going to be hearing more of."

Other notable artists Weaver has performed with include: Adonis Rose, Amina Figarova, Bill Summers, Brian Lynch, Christian Winther, Corey Fonville, Dee Dee Bridgewater, Delfeayo Marsalis, Don Byron, Ellis Marsalis, Emmet Cohen, Germaine Bazzle, Godwin Louis, Herlin Riley, Jamison Ross, Jeremy Pelt, Joe Dyson, Jon Batiste, Juvenile, Lucien Barbarin, Mannie Fresh, Maurice Brown, Mike Clark, Nicholas Payton, Quiana Lynell, Sasha Masakowski, Shannon Powell, Stefon Harris, Steve Masakowski, Steve Turre, Sullivan Fortner, Terell Stafford, The Session, Theo Croker, Victor Goines, Vincent Gardner, Wayne Escoffery, Wes Anderson and more.
