Top 10 Ritchie Blackmore Guitar Moments

I think this is his best solo but because the song isn't well known, it's usually underrated.
The riff is great, too.

Besides the solo and some other well known things, this was the first metal-related song with tremolo picking - a technique that was widely used later in extreme metal, such as black and death metal (also in some power metal).

For me this is 1st metal song ever, 1970 (not perfect, not the best by Deep Purple but it started something new that is important to me)

The riff - it was ripped off by over 10 metal bands, including Dream Theater (Panic Attack).
This song is mostly known by metal musicians and die hard fans. A very underground song.

The riff AND the solo, plus the symmetrical Arabic scales he used (unique approach)

The solo - fast, technical, melodic

Killer riff inspired by Beethoven
