Ryan Gould began his musical life with the guitar. His study of guitar led him to play the death metal and punk rock of the late 1980’s and early 1990’s in bands around the Philadelphia area. After his service to the country as a United States Marine, Ryan returned to southeastern Pennsylvania with a keen interest in traditional Irish music. He began studying the uilleann pipes with the great Irish piper, Roy Rogers. Irish music aroused in Ryan a heightened awareness of American folk music that led him to bluegrass, then jazz, and on to his new home, Austin, through the string bass.

Ryan arrived in Austin in 1999 ready to work, helping to form bands like Shorty Long and Les Niglos. He subsequently found himself working with such Austin luminaries as Erik Hokkanen, Floyd Domino, Wayne Hancock, and The Jazz Pharaohs.

Presently, Ryan can be found regularly on stage in Austin, Texas with Erik Hokkanen and The Hip Replacements, The Jazz Pharaohs, Aunt Ruby’s Sweet Jazz Babies, Giant City/Three, Falletta and Her Fellas, The Floyd Domino Trio, The East Side Dandies, and The Big Jug Band; and, occasionally, in San Antonio with The Jim Cullum Jazz Band. He draws great inspiration from a vast pool of musicians of many different genres and eras as well as from the experiences of his daily life.

Ryan has been lauded by his peers as a great musician and bassist, with whom it is a pleasure to create and share music. In 2012, he became a co-founder of the Hot Rhythm Foundation and an organizer of Hot Rhythm Holiday.

A native of Monroe, Louisiana, Albanie was in her formative years exposed to the local music of Louisiana: the sounds of cajun, zydeco, blues and gospel musics at festivals and backyard parties. Shortly after relocating with her family to San Marcos, Texas at the age of nine, Albanie began taking guitar lessons and developing an interest in acoustic-roots and electric blues, punk rock, and hair metal. Albanie began her love and study of early American Jazz as a freshman in highschool in Wimberley, Texas, when she was exposed to the Parisian Romani guitarist Django Reinhardt. Listening fervently to recordings of Reinhardt, Louis Armstrong, Billie Holiday, Fats Waller, and other such great figures of jazz, she began to develop her feel for swing. Soon she was performing alongside mentors and other players of the Austin scene where she lived and performed in the years after high school. In the summer of 2013 Albanie relocated to New Orleans, Louisiana, where she is currently living and performing with various traditional jazz and swing ensembles.
