Recommended acoustic recordings

Second Eva Cassidy, especially the Songbird album on vinyl.

Opus 3 - Thorvald Fredin, "Concertos for Double Bass & Orchestra" SACD 8522 - classical music for orchestra and double bass by Bottesini, Erland von Koch and Lars-Erik Larsson. The Larsson piece is particularly fine.

If you don't know the recordings on the Opus 3 label, I encourage you to explore them. They are all acoustic and exceptionally well recorded with emphasis on getting a capturing the timbre of instruments and reproducing the original performance space as naturally as possible.

I have a bunch of Opus 3's, but not the ones recommended. I will explore those mentioned. Thank you for the responses everyone. A few examples of recordings that really shimmer on my simple setup (and most are regular RBCD's):

- The Florestan Trio, Debussy/Faure/Ravel

- Grieg, Peer Gynt, Sir Thomas Beecham

- Helge Lien Trio, hello Troll

- Julian Lage, Sounding Point

- Brian Bromberg, Wood

- Anouar Brahem, The Astounding Eyes of Rita

Norah Jones esp. her 1st two albums
Melody Gardot esp. My One and Only Thrill
Ben Harper esp. Disc 2 of Live on Mars
Lyle Lovett esp. I Love Everybody

"Telluride Sessions" by Strength in Numbers
"Migrations" The Duhks
"The Duhks" self titled
"Hotel Child" Ingrid Lucia and the Flying Neutrinos
Four standard CDs that have great sound and great music.
There is electric guitar on "Hotel Child"
