I play mainly acoustic, finger picking and blues styles. I find that sometimes I need to cut through the mix a little more. Best electric? Go.

According to a new paper published today in Nature Materials, the newly engineered material creates a robust acoustic structure that can control in unusual ways the propagation and localization of sound even when fabrication imperfections exist. This unique property may improve technologies that use sound waves, such as sonars and ultrasound devices, making them more resistant to defects. Using topological principles, researchers predicted and later discovered topological insulators—special materials that conduct electric currents only on their edges, not in the bulk. Their unusual conduction properties stem from the topology of their electronic band gap, and they are therefore unusually resistant...

Lovely cover of Junior Kimbrough’s Hill Country classic, “I’m In Love With You”.

Great clip of Ian Gillan, live and unplugged, singing a couple of his hits.

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets. The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and...

Friendship Song (original acoustic) Listen at: http://www.youtube.com/watch?v=-FrRsrc19pg You look past mistakes I've made All the hands that I misplayed. Always have a friend to call. Lift my spirits when they fall. You turned 'round to lend a hand. "Here to help." "I understand." I was stranded on the road Fearing my car might explode. I was bedbound late in life Missing my departed wife You came by to share a meal, Lend an ear, ask how I feel. Thank you for the joy you bring You have given everything Don't deserve the gifts you share Thank God I have friends...

Ancient Architectural Acoustic Resonance Patterns and Regional Brain Activity Authors: Cook, Ian A.; Pajot, Sarah K.; Leuchter, Andrew F.Source: Time and Mind, Volume 1, Number 1, March 2008 , pp. 95-104(10)Publisher: Berg Publishers Abstract: Previous archaeoacoustic investigations of prehistoric, megalithic structures have identified acoustic resonances at frequencies of 95-120 Hz, particularly near 110-12 Hz, all representing pitches in the human vocal range. These chambers may have served as centers for social or spiritual events, and the resonances of the chamber cavities might have been intended to support human ritual chanting. We evaluated the possibility that tones at these frequencies might...
