Gems of raja under various genres of music

[crajkumar_be]

Getting back to instruments - hard rock is definitely identified the electric guitar whose sound is driven to distortion, using feedback. The guitarist plays it in front of the speaker (driven by the guitar amplifier) and the microphone picks up the sound from the speaker (its own sound) as well.

Classic rock (Eaglies, Santana /w samba influences) drums and bass guitars to maintain rhythm. Some amount of strings was also used. This was the most popular (POP) form of music for a long time (before the dance club/rap scene). I consider IR's music to be born out of this genre of music for most practical purposes. Listen to Simon and Garfunkel you will notice the similarities.

Psychedilia, to me seems, like a or one of the special cases. Because it is based on the feel it creates (dreamy/drug induced state). If I remember, the hero in thoongAthE thambi thoongAthE , is a drug addict. I think IR instinctively must have come up with this effect (he surely has had a good listening of classic rock genre).

Kiru,
Just my 2 cents:
Classic Rock, as a genre broadly refers to rock music of the "classic" years (60s-80s) and it encompasses country/blues/folk rock (CCR, Allman Brothers Band, Cream etc), jazz/rock (Steely Dan), psychedelic/progressive rock (Pink Floyd, King Crimson etc), hard rock (Led Zeppelin, The Who etc)...
IMO its more a time-based grouping of various sub-genres of rock.
