Loud as a jet engine being fired up, while also dropping incredibly catchy earworms. That was Mondolux.
I saw them many times... at Canal Street Tavern, at El Diablo (anyone remember that spot), in a tiny room upstairs at Southgate House. They were my first live experience with punk-adjacent music. I say "punk-adjacent" because the songs were generally hooky rock and roll with all kinds of pop sensibilities... just played really really loud and usually rather fast. Also, recently, I was watching a video of The Clash playing live, and recognized many of the musician stances and mannerisms as something I had seen at Mondolux shows... these guys must have loved The Clash.
Alas, this band is no more... and you can't find a great deal of their music online. Here is one of my favorite of their songs, called "Memphis Lung". What's not to like here? This one has a nifty little swagger to it, a fantastic groove, and Eric Purtle's charisma comes across just fine in this recording... but that's nothing compared to what it was like to see them do this live.
Here's a video taken from one of their live shows.
This song is "TJ Swann", and is on their last album. A pop song. Catchy, with the volume cranked. That was Mondolux.
