“1990’s Seven Turns was a tentative comeback for (the Allman Brothers Band), which had gone nine long years without making a record,” (Ultimate Classic Rock). “Sparked by some new members, including guitarist Warren Haynes, the Allmans were blazing forward when they returned with Shades of Two Worlds. Haynes has a bigger role on the record, cowriting more than half of its songs. Veteran member Dickey Betts also turned in some of his strongest numbers.
… ‘There was just so much freedom, so much space,’ cofounder Butch Trucks told the Los Angeles Times in 1991. ‘For the first time since Duane (Allman) and Berry (Oakley) both died, there was a group of guys all going in the same direction, all feeling the same type of music and energy. It really (had been) a problem since that long ago.’ … Rooting themselves in tradition also set this lineup apart from the band’s doomed second edition, which saw what became a more pop-leaning 1978 comeback bid fizzle a couple of years later. Shades of Two Worlds would instead hearken back to the lengthy improvisational excursions found on 1971’s At Fillmore East, the last complete recording featuring Duane Allman.”
After starting in C minor, the instrumental track “Kind of Bird” shifts to Eb minor at 1:05, then cycles through both keys again before introducing an E minor section at 2:16. Angular melodies and the occasional odd meter keep listeners on their feet throughout the tune!
