Digitally remastered release combines two separate albums (Volcano and Rue Chaptal) that were recorded during the same evening at Ronnie Scott's, consisting mostly of originals by Boland, with a cooking Blues feature, "Griff's Groove," showcasing Griffin and Bailey, especially standing out. Clarke composed the explosive "Volcano" as a feature for himself and fellow drummer Kenny Clare. Woode, a veteran of Duke Ellington's band, penned the gospel-inflected blues "Now Hear My Meanin'," which has soulful solos by alto saxophonist Derek Humble, trombonist Ake Persson, and baritone saxophonist Shihab.
