想像ですが「レコード会社と契約もあるし、どうせつくるなら自分が好きな音楽をやりたくって、いつものメンツに声かけたら皆が参加したいってことになったぜ」って感じでしょうか。流行りのロックよりブルース色を押し出し、Clapton の趣味を強く感じる作品となっています。全15曲のうち Clapton の作曲は Run Back to Your Side のみで他は全てカバーとなっています。私も知っている大物は、Sheryl Crow、Derek Trucks、J. J. Cale、Allen Toussaint、Wynton Marsalis などですがレコーディング・メンバーの多さにはビックリです。予定の調整も大変だろうしギャラだけでも物凄い金額となったことと思われますので、売れるのが確定のロックスターでありポップスターの地位を確立したアーチストでなければ出来ないプロジェクトですね。
