Ambient noise is typically the sort of thing people can only take in small doses-if they can take it at all. Ambient noise as long-form jam? In a box set of five LPs? You might need one hand to count all the die-hard fans for that. All of which makes violinist/composer Liz Meredith and guitarist/composer John Somers The Disposition of Vibrant Forms a minor miracle: five side-long tracks of warm, amorphous ooze that engages the brain as much as it pleases the senses. Think of it as the soundtrack to an imagined abstract film being projected onto the backs of eyelids for about three hours.
