Hyla's "Pierrot ensemble" work Field Guide uses multiple influences. Vance R. Koven (The Boston Musical Intelligencer) writes, "Like Messiaen, Hyla has a weakness for birdsong, several of which he has incorporated into this piece. Our ornithological chops being weak, especially for the mostly exotic species Hyla imitates, we can't comment on authenticity or really recognize them as what they are, other than as motivic raw material. Hyla weaves these fragments among passages offeriving rhythm connected, he writes, by snippets from Donovan's Wear Your Love Like Heaven." For advanced performers. Dur.: c.9'
