The I-Spy music was great.
There were actually 2 I-Spy LPs: One on Warner and one on Capitol. There is/was also an I-Spy CD available from Film Score Monthly.
I'm a sucker for that eastern-tinged psych-jazz. All of Gabor's Impulse and Skye albums are worth picking up. Also, Chico Hamilton's 60s Impulse albums with Gabor on Guitar.
One of the coolest instruments ever. I will be happy to take any CDs or LPs off your hands with celeste.
Villa Lobos and Les Baxter, two giants of 20th century music, used the celeste to great effect.
