This piece was commissioned by a great friend of mine and fellow bass trombone player, Jeremiah Ward. The piece is in four movements, each based on a different kind of beer. Jeremiah, who has spent significant time working in different breweries while pursuing his playing career, provided me with wonderfully descriptive and in-depth ideas of the flavors and ways these different beers are made, which really helped to create the foundation for the structure and harmonic progressions of the piece. Barlines is an intensely challenging piece constantly growing in difficulty as the piece progresses. Harmonically this piece is one of the most mature I have ever written, with more dissonance and extended harmonies than I have used in most of my past works. The melody much like my other pieces is quite angular and aggressive, but still has moments that can really sing out and show off the large, dark tone of the bass trombone.
