Ever since the extravaganza of the YouTube Symphony’s premiere of Mason Bates’ Mothership at the Sydney Opera House in 2011, the piece has taken off (sorry), popping up in the programs of major orchestras across the US and abroad. Mothership is perhaps the most direct and largest-scale representation of Bates’ style as an ensemble composer, which blends contemporary American classical composition with jazz and electronic sounds. Its driving, grooving feel is positively addictive, like Short Ride in a Fast Machine seen through a smoky jazz/electronic kaleidoscope.
