Nightbloom is the collaborative album by ambient musicians Steve Roach and Mark Seelig, containing Mark's vocal and Tuva-style overtoning, combining Steve's zones and grooves.

[1][3] The first track features a slow rising and falling bass tone for the first eight minutes until a subtle percussion pattern begins to emerge slowly from deep in the mix.

The second track brings a drumming loop, further laden with echo as the main drones continue steadily.

AllMusic rated the album a 3.5 of 5, saying "it's enjoyable more than remarkable, but Roach and Seelig are nothing if not listenable composers for a variety of moods".

Hypnagogue highly rated the album, saying "Nightbloom has taken me to amazing places and shown me incredible things every time I’ve listened".
