At its core, it's an ambient album, filled with spacy, synthetic textures, repetitive keyboard lines and sound effects. Miles uses ambient as a foundation, and he often spins off into dance-club tracks where divas (either Kathy Sledge, Nancy Danino or Barbara Prunas) sing his humanistic lyrics. There are interesting ideas throughout 23 AM, but they're not always executed well -- often, the ambient interludes are meandering and the vocal tracks are colorless -- but there are enough interesting moments to make the album of interest to any fan of Dreamland.
