Avoid "Texas Six Pack" like the plague! They butchered the mixes of their 70s lps with 90s drum samples and the results are criminally bad.
For cd, the Chrome, Smoke & Barbecue or Rancho Texicano compilations have a good selection of their early material with un-fucked-with sound but
their first 4 or 5 LPs on vinyl are the ideal way to go.
i would even recommend the 90's studio albums,
they're cheap $2-$4 and have a great dirty sound
good to see you sakedelic, hope all is well in the big Apple
