Harmonious Wail are purveyors of Americana infused Gypsy Jazz that continues to take their listeners on a ride via the music of the Hot Club sounds of Paris to the deepest blues of the Memphis Delta to the folk scenes across “every town” America. The Wail are sublime entertainers, great educators and they’ve mastered the art of lifting spirits.

Harmonious Wail is Sims Delaney-Potthoff, a mandolin virtuoso, bandleader, vocalist and master of all things behind the curtain, Maggie Delaney-Potthoff, vocalist extraordinaire whose percussive instrument of choice is a cardboard box, but who also has a knack for exploring the musicality of almost any household object, and Jeffo Weiss, a master bassist who dazzles and mesmerizes on both upright and electric 5-string bass.

Every performance is played from the heart and infused with the perfect balance of ingredients that firmly proves that music truly does make the world a better place. The Wail celebrates 10 recordings in their 30 years of existence and is currently kicking off their 4th decade recording a new CD that teams them with a group of Gypsy Jazz All-stars.

Their gracious approach to music translates beautifully in any outreach program. They have honed their skills to provide excellent educational programs tailored to fit groups of varying skill and age. Popular topics have included; ”the instrumentation of Gypsy Jazz”, “how to succeed in the music biz”, and Maggie’sMethod™ “If You Can Speak You Can Sing”.

Not only a touring band the ever reaching Harmonious Wail has enriched their lives working with National Public Radio by performing on multiple shows and even donating songs to use in annual fundraising campaigns. They have founded multiple charitable organizations placed music in film and recently received the 2017 Musicnotes Outstanding Musical Career Achievement Award.

As stewards of the Gypsy Jazz genre, they founded and have grown the Midwest Gypsy Swing Fest over the last decade and have begun to take the show on the road as a special concert package bringing amazing musicians from around the world together and placing them in front of concert audiences throughout the US.

Sims Delaney-Potthoff
Sims Delaney-PotthoffMandolin, Vocals
Sims Delaney-Potthoff, Harmonious Wail’s founder, leader and mandolinist , credits Jethro Burns with the band’s unique, enticing style of mandolin-driven gypsy-jazz. Sims studied for seven years with Burns, the legendary jazz mandolinist, laying the foundation for Harmonious Wail’s acoustic string sound. He furthered his studies with Matt Glaser at Boston’s Berklee College of Music, honing his skills while immersing himself in the “gypsy” music of Django Reinhardt and Stephane Grappelli (Lester Young, Charlie Parker, Bireli Lagrene, Duane Allman, David Grisman, and Louis Armstrong are also on his list of musical heroes). Sims also plays a 1937 Gibson Tenor Guitar (tuned as an octave mandolin), sings, writes and arranges for the Wail. He founded the group in 1987.
Maggie Delaney-Potthoff
Maggie Delaney-Potthoff Vocals, Percussion
Vocalist Maggie Delaney-Potthoff is a captivating performer. Equally at home scatting over a bebop tune, soaring on a solo, or blending with the Wail’s tight vocal harmonies, she delivers both powerhouse tunes and ballads with confidence and ease. Her sensual, sinuous movements (a product of her background in dance and theatre) and her use of a cardboard box played with brushes as a drum add to the charm she exudes onstage.
Jeffo Weiss
Jeffo WeissBass
Jeff Weiss, recent graduate of UW-Madison’s School of Music, is already a master bassist with dazzling artistic prowess. Awarded the 2012 Madison Area Music Award for best bassist of the year, Jeff brings to the Wail a mesmerizing technical facility on the fretboard, a sophisticated and versatile style, and a powerful ability to create musical ambiance and rapport. Jeff studied under Richard Davis for five years and was principle bassist for UW-Madison’s Symphony Orchestra. Jeff’s music reflects a broad application of classical and jazz influences.
