String quartets.

Adagio for Strings

Spiegel im spiegel - Arvo Part, the purest music out there, i like the cello and piano arrangement best.

Romantic-era classical piano.

Not one, many Indian Classical, aka Hindustani Classical music using instruments like, Tabla, Sitar, Veena, Santoor, Bansuri, etc.

I like this Veena(not Sitar) performance of Breathless(original song by Shankar Mahadevan) by Veena Srivani
