Damn gh, you nailed Evan's sound! His Surf element is what got us the gig for the album. By the way, the original drummer in The Hillbilly Soul Surfers was Pete Curry, now bassist in Los Straightjackets. Pete's an old friend of mine from San Jose (since '62!), and he switched from drums to bass in The HSS so we could play together. He got the offer from The 'Jackets before we recorded with Evan, and now gets to tour with Nick Lowe. Rat bastard!
You're right, Danny was a very technical player, Evan a more instinctual one. The guitarist many great players (including Danny and Evan) revere is not very well known to non-musicians: Merle Travis. Merle was the model for ALL the Country and Rockabilly (and many Rock 'n' Roll) guitarists who followed him, including Scotty Moore (early Elvis), Dave Edmunds, George Harrison, and Jeff Beck (who idolizes Merle). Danny was also a very Jazz-influenced player, Evan not so much. But Danny wasn't a songwriter, or a singer. When Danny and Evan were together, Danny "just" played guitar, Evan wrote and sang the songs. Never got to see them together, damnit.
I too love that first Mason Ruffner album, it's a beaut! I have it on LP, and his Evolution album on CD. Wonder what became of him?
