No matter how many decades pass since its 1960s heyday, our collective fascination with the jam band refuses to die. One only has to look at the ever-increasing number of street fashion brands reinterpreting the Grateful Dead bootleg lot tees of yesteryear to get a sense of the innate allure that the jam band lifestyle still holds in our psyche (even if it means people are spending more money to see John Mayer than they could have ever imagined). Of course, beyond the hypnotizing tie-dye and the communal joy of taking psychedelics and dad-dancing in a field with your caravan for three hours, there's the music.
Tremolo may be one of the oldest guitar effects, but when done right, it's definitely one of the trippiest. Take, for example, "What Has Happened" by Tonstartssbandht, the lead single from the duo's new album, Petunia. The stroboscopic throb of Andy White's tremolo guitar pans back and forth between the stereo channels, giving the song its steady but disorientating pulse.
