@bdp24 - You are like some walking encyclopedia of popular music! After reading your first mention of him here , I did some quick searching this AM and listened to a few songs with the H Bombs (Madhouse & Saving Grace) on You Tube.
I can hear the rock-a-billy thing (never was a big fan) but to my ear, at least, what jumped out is a surf guitar/Dick Dale kind of sound. Regardless, I immediately liked those couple of EJ songs...more so than the stuff I heard of Gatton’s on a lengthy compilation (can’t recall title). My impression is Gatton might be the superior technical player but Johns’ got more "soul" or
something (exhibit A: Love is Murder). On the other hand, I might be talking out my...but that’s the initial impression.
In the bit of reading I did, came across this: Evan’s Story
https://www.youtube.com/watch?v=tEVbbgI8OaI&ab_channel=foundcom1You know anything about Mason Ruffner? He was supposed to be the next big thing a while back. Jimmy Page produced his first LP (Gypsy Blood, I think). Could look him up I suppose but interested in your O-pinion. There’s something of the rock-a-billy/Link Wray in him as in the above.
Got "The Jungle Record" playing now. Couldn’t quite recall who EJ’s vocals reminded me of. On Day Go By it clicked. There’s something of Eric Burdon happening there. That’s okay with me.
