In the midst of his second European tour in the last six months Trombone Shorty (Troy Andrews) was joined by his mentor and former bandleader Lenny Kravitz, who surprised Troy’s fans onstage in Paris on October 13th to sit in on drums. This was followed by a late-night session in the studio, where Andrews added some touches to Mr. Kravitz’ upcoming CD, which already includes horn parts Troy had recorded at Lenny’s studio in Caribbean.
