The arsiest man in rock!

The "Bastard in Black"!

Ritchie Blackmore is the amazing former Deep Purple guitarist best known for his awesome riffs like "Smoke On The Water", "Black Night" and "Burn". He's famous for being a bit temperamental (or sometimes just plain mental with a hot temper)...

Blackmore quit Deep Purple in the mid 70's to start a new heavy rock band called "Ritchie Blackmore's Rainbow" with future Black Sabbath vocalist Ronnie James Dio. The name was later shortened to "Blackmore's Rainbow" and then just plain "Rainbow".

The original Rainbow bass player, keyboard player and drummer were soon replaced by Jimmy Bain (formerly of Street Noise and Harlot), Tony Carey (formerly of Blessings) and Cozy Powell (of everyone else). This is probably the most popular Rainbow lineup.

Ritchie Blackmore now plays guitar (NOT lute!) with Blackmore's Night.

To have intercourse while wearing only a sweater and sox, the way Ritchie used to on the classic "Happy Days."
Mary-Beth Allen insisted that Ritchie Cunningham take off only his pants and tighty-whiteys when they screwed. She insisted it made his Pinky Tuscadero seem almost twice as large. It soon became all the rage, thanks to the graffiti on the ladies room wall.

Ritchie Valens was an amazing man who cared a lot about his music and family. Sadly Ritchie‘s life ended alongside fellow musicians Buddy Holly, J.P. Richardson professionally known as the Big Bopper, on February 3rd, 1959 in clear lake Iowa from a plane crash. Ritchie was terribly afraid of planes ever since his friend was killed by a falling plane when he was younger. If you’re interested in more about Ritchie I suggest watching the 1987 film La Bamba.
R.I.P Ritchie valens you are a legend, just remember, the sky belongs to the stars.
