Releases are usually taken from recordings of concerts in the club. A late 2014 list of recording equipment included: "a matched pair of Schoeps Mk. 4 and a Neuman U87 microphones on the piano; U47 and Royer 122Vs on tenor sax; RCA 77 ribbons on alto sax; a vintage
RCA Type 44 and a Coles 4038 on trumpets; an RCA 44 and Sennheister 409 on bass; and, for drums, a pair of Neuman KM84s and a Coles 4038 overhead, a D12 or FET47 on the bass drum, and an SM57 on the snare". ==References==
