A graduate of the University of Southern California’s Thornton School of Music, Daniel works professionally as a saxophonist, keyboard player, and singer. Daniel has played with jazz luminaries such as Frank Wess, John Daversa, Bob Mintzer, and Joshua Redman, and has appeared in the Academy Award-winning film "Whiplash," on the television show “Glee,” and on the third season of NBC's primetime show "The Sing Off."
Daniel works regularly as a studio musician on saxophone, flute, vocals, and keyboards and has recorded on film scores, hip-hop tracks, and world music albums as well as jazz recordings. One such jazz recording entitled “Fourteen Channels” on the Tapestry Records label cracked the top 50 on the US Billboard jazz charts and featured Weidlein’s improvisational work as well as his composition “An Ounce of Hope.”
Daniel's work as a composer spans independent films, CHOSEN (2014), and upcoming feature, SLEEPWALK (post. 2021), as well as the new musical, THE GRIFTERS (book & lyrics by Joe Giuffre). In 2018 he released FIRE IN THE SKY, his first collection of contemporary jazz compositions written for rhythm section, winds, and strings, followed by the 2019 release of A WINTER'S LULLABY. To celebrate the release of these collections, he released a separate vinyl edition of the three-movement piece, THE RED LINE SUITE, available on vinyl.
Daniel's style as a composer bridges the groove and rhythm of jazz through the decades, with his love of classical composition and a contemporary folk sensibility. The latter influence is particularly present in his musical collaborations with jazz trio The Vintage Modernists (CITYSCAPE, 2012).
Among Daniel's favorite pieces that continue to inspire him to this day, are the reimagined Joni Mitchell album, BOTH SIDES NOW, featuring Vince Mendoza's orchestrations, any of Randy Newman's film scores, and Brad Mehldau's HIGHWAY RIDER.
