Pisces is the 12th sign of the zodiac, and is the slippery fish in the deck.

Elusive and mysterious, unknowable and sometimes a little remote, they are most comfortable in the realms of their own mind. They are deep intuitive thinkers; yet rarely want to share their deepest thoughts.

Of all the signs in the Zodiac, Pisces counts the most musicians among its ranks — and the most brilliant and inventive

Often introverted, they are rarely loud or boisterous, and would rather let their works of art, their uncanny creations, or their outrageous clothes speak for them. (We’re talking about you water baby, Rihanna.) It is no accident that Piscean George Harrison was known as the “quiet “ Beatle. Although, when they feel they are misunderstood, or someone tries to break through their carefully cultivated subterranean cave, or even dares to ask them what they’re thinking about, a Piscean native can be downright nasty.

If you don’t believe it, think of Lou Reed’s sometimes off-putting temper, his sardonic retorts or just the song “Vicious.” Jazz singer Nina Simone sang like a fallen angel in her expressive contralto, but most people still remember her fiery temper and frequent anger management issues or the time she fired a gun at a record company executive, whom she accused of stealing royalties.

But despite her intimidating personality, Simone exhibited another of Pisces characteristics — idealism and the desire to help those in need. In fact, if you’re planning a benefit, call a Pisces. Simone is remembered equally for being a civil rights activist after she openly addressed the racial inequality in the United States when she released “Mississippi Goddam,” her response to the bombing of a church in Birmingham, Ala., that killed four pre-teen black girls, as Harrison is for his Concert for Bangladesh.

Ruled by Neptune, the planet of inspiration, dreams, illusion (and confusion), it also holds sway over the subconscious, fantasies and the imagination. Of all the signs in the Zodiac, Pisces counts the most musicians among its ranks — and the most brilliant and inventive.

Always at war with matters of the flesh and spirit, self-indulgence and self-denial, most  Pisces dwellers have a proverbial angel on one shoulder and a devil on the other

Brian Jones, was by far the best musician in the Rolling Stones, pushing them to more daring feats of musicality once they graduated from being a blues cover band when they first began back in 1962. It was Jones who came up with those backward guitar solos, and it was he who peppered the Stones early music with not-typical-at-the-time instruments such as the sitar and marimba, which were integral to the distinctive sound of the band. He also introduced them to psychedelia, both the musical form and the drugs; unfortunately, Jones showed another more lamentable Pisces characteristic — a fondness for drugs and inebriants.

Neptune, often called the Lord of Illusion, governs drugs — both those medicinal and recreational. It’s no surprise that far too many Piscean musicians have shown a fondness for intoxicants, such as Libertine founder and one-time Kate Moss escort Pete Doherty, the aforementioned Lou Reed, James Taylor, Kurt Cobain and Johnny Cash. Not so oddly, Pisces also rules hospitals and rehab facilities, so a complete recovery from addiction is possible, usually when a Piscean is of middle age.

The last of the three water signs, Pisces also rule over rain, ice, and liquids of all kinds, including beverages and alcohol, which may explain how Brian Jones met his death at the bottom of a swimming pool.

Speaking of water, have you ever looked at the symbol for Pisces? It’s the image of two fish swimming in opposite directions. Some insist it signifies that a Piscean native can never make up their mind — which is certainly true — but more than that, the image represents the conflicting desires of those folks born between February 19 and March 20.

Always at war with matters of the flesh and spirit, self-indulgence and self-denial, or more simply said, most of the dwellers of this sign have a proverbial angel on one shoulder and a devil on the other, and they are always in dialog with both sides.

If you don’t believe it, just listen to Stromae’s “Peace or Violence.” Maybe the most perfect example is The Head and the Heart, who incorporated that duality into their own name, certainly because three members — Jon Russell, Charity Rose Thielen and Kenny Hensley are all Pisces.

Spiritual, mystical and intuitive, don’t be surprised if your favorite Piscean musician can actually read your mind. By trusting their natural intuitive ability to read people and situations, Piscean musicians are especially adept at improvising and jamming, where their unrestrained creativity can truly soar. The king of them all, the potentate of free jazz and the prophet of all things metaphysical Ornette Coleman proved this over and over — but never the same way twice.
