[LottiFurmann]

Tend to agree with Kalai. There are number of such albums.
THIRUPPAAVAI - Pasurangal sung by PS. We are used to here the pasurams rendered by various artistes in Marghazhi. One should listen to this cassette. Music by LS SriMuralle. The prononunciations and the clarity of rendition.
One more rare gem is THIRUMURUGAN THIRUPALLI EZHUCHI(Lyrics - Thamizhnambi: Music-Karumpiyan).
Many more. To name some:
