Great Lost Lps...

Sticking with some other 70s horn bands that I love to pull out:

1: Blood Sweat & Tears - pick from either "Child is Father to the Man" (this is their 1st LP before David Clayton Thomas joined the group and sang on their self-titleld Grammy award-winning 2nd LP) or "BS&T 3" the album right after that self titled LP.

2: Lighthouse - "One Fine Morning"

3. Buddy Miles - "Them Changes"

4. Cold Blood "Sysiphus" or "First Taste of Sin"

5. Tower of Power - "Back to Oakland" (OK I lied, I play this one all the time)

The Great Lost Kinks Album

Richard Thompson - Live (more or less) or guitar/vocal, toss up between the two.

Lou Reed - Take No Prisoners

Boz Scaggs (self titled, 1969)

Television - Marquee Moon

buckingham and Nicks
Agree with Crack the sky--animal notes
Climax blues band
Pousette-Dart band--County line album

Spirit-"The Twelve Dreams of Dr. Sardonicus"
Chicago Transit Authority
Boz Scaggs (self titled, 1969)

All 3!, heavy rotation back in the day & still check them out on a the rare day.

And off the top, how about:
Hawkwind
Rock 'n' Roll Animal - Reed, Wagner, & Hunter
Brian Auger's Oblivion Express
Opafire "Ricochet Sun"

Blues Image - Open
Spirit - Clear
Chase - Pure Music

(and a second to all the great suggestions by others above)
