Simon Williams has a great rainstorm mixed with minimal echoed piano and synth washes/textures release entitled Gentle Rainstorm
. Here's my review of it from years back (but it's stil available...see link below)
Stretching out over more than sixty-minutes, Simon Williams' Gentle Rainstorm CD is one of the most calming yet reflective recordings I've heard in a while. Combining a Tim Story-like melancholy piano line with patient synths and synth choruses, the single song ("Gentle Rainstorm") unfolds so slowly that it would be difficult not to find oneself unwinding as the music plays out at its relaxed pace. What impressed me almost right away was the emotional neutrality (or even somberness, at times) of the music. This is not syrupy, sugary or overly "pretty." Instead, it is, at times, almost Zen-like in its feel (and subsequent effect). The accompanying sound effects are used with utmost discretion and are comprised of falling rain and occasional thunder. Simon exercises remarkable restraint with his piano playing, never veering into quasi-Lanz territory, so that the music maintains an ambient sensibility throughout. But, there is also a warmth present in the music, ev en when it (the music) is reflective and moody, that makes this CD a natural for late night listening or as accompaniment to contemplation. The music itself evolves quite a bit as the album progresses. Synth strings are emphasized, then subside. The piano varies from being quite minimal (even disappearing for stretches) and then carrying the melody in the forefront. A synth oboe/recorder occasionally weaves a gentle and sad melody line over the soft keyboards. All these distinct textures and "movements" makes Gentle Rainstorm a constantly interesting (and even more enjoyable) recording in which to immerse oneself. Ambient music fans who sometimes wish for something a little friendlier than standard noir (dark) recordings will, I think, enjoy the relatively unstructured feel of this album, as well as its lack of phony sentimentality (at times, such as when the piano is under-emphasized, this is closer to space music or ambient artists like Jon Mark or Mike Simmons). Albums like Gentle Rainstorm are a mainstay of my weekly listening agenda. In particular, Simon's ability to create relaxing yet never "sweet" soundscapes makes this a CD that will seldom (if ever) be "shelved" and will likely be left out on the CD player for those times when stress and mental "wear-and-tear" require a thorough cleansing of my psyche. For just such a purpose, Gentle Rainstorm is a revelation. Peaceful yet laced throughout with a sense of beautiful melancholy, this is indeed music for quiet times. Highly recommended!
Here's the link and there are two short sound clips,although the album is one long track. It will give you an idea what to expect.http://www.svpworld.com/dnn/Styles/Stylestopurchase/tabid/60/CatalogItemID/34/CatalogID/3/psnavcmd/CatalogItemDetails/psmid/-1/Default.aspx
