Sweet Home Alabama (Electric Version)

All of us know this song, all of us like it, all of us recognize it when we hear it (always played in Oktoberfest), but never in my life I would think to play it as in the following video. The creators Eric Goodchild and Steven Caton built two gigantic tesla coils to generate different sounds with the sparkles and stuff… well, the result is very impressive and absolutely fun:

According to the description of the video:

The primary drive system for the coils consists of high power semiconductors arranged into an H-Bridge switching configuration. During a spark event, the coil is pulsed on for a few hundred millionths of a second. During this short time, thousands of amps circulate within the primary tank circuit and the energy is coupled into the secondary resonator through magnetism.

So what appears to be a continuous burst of sparks is actually a specific number of sparks generated per second. By modulating the number of sparks that emit from the coil each second, different tones can be produced by the coils.

Have a look to their videos, they’re not only playing that song, but also have many other different hits such as In the Hall of the Mountain King, Pirates of the Caribbean, House of the rising sun, Dueling Banjos, etc. Check also their channel, they have cool shit with lasers and stuff.

Science fucking rocks!

La canción del día

Claro, no podía faltar en esta nueva sección la multiorgásmica rola “Free bird” de Lynyrd Skynyrd (se pronuncia Linerd Squinerd). Esta canción se lanzó en Agosto de 1973 dentro del álbum del mismo nombre (Lynyrd Skynyrd). La primera vez que escuché esta canción fue en la película “Forrest Gump” cuando Jenny se pone sobre el balcón como para tirarse, pero fue solamente un pedacito, nada que sea bien apreciable.

Tiempo después la invoqué de nuevo cuando comencé a tocar la guitarra. ¡Uuuuyyyy! Hasta se pone la piel chinita con tan sólo escuchar la introducción con el piano tipo Gospel y el rasgueo suavecito de la guitarra acústica.

¡Pero no, señores! Free bird no se queda ahí. La guitarra de Rossington se clava en un slide bien melódico desde el inicio. Entonces Van Zannt empieza a recitar como si le estuviera hablando al oído a su morra. Uno nomás cierra los ojos y se imagina estando con su pareja.
