Cool Change is an American Rock Band!
Influenced by 1960s rhythm and blues, soul, bluegrass, and rock bands such as the Byrds, Springfield, and the Eagles', Cool Change overall sound has been described as "California rock”
"No one knew quite what 'California rock' meant – except perhaps that, because in California anything was possible, music that came from that promising land was more free-spirited and free-ranging".
A combination of "country-tinged vocal harmonies with hard-rock guitars and lyrics".
Similar bands included The Eagles, Poco, Firefall, Pure Prairie League..... maybe even a little ZZ Top & Lynyrd Skynyrd.
