Not Two Records celebrates their 20th Anniversary with a festival in Wlen, Poland, inviting 13 of the finest European & US improvisers--Guy, Leandre, Mazur, Nilssen-Love, Kaucic, Fernandez, Gustafsson, Vandermark, Trzaska, Brotzmann, Swell, Holmlander, & Homburg--performing in configurations from duo to quintet, released in a limited 5-CD wooden box set.

Hailed as the most pyrotechnic and adventurous concert of the 12th Ad Libitum Festival in Warsaw, Poland, the collective quintet of Agusti Fernandez on piano, Artur Majewski on trumpet, Albert Cirera on saxophones, Rafal Mazur on bass, and Ramon Prats on drums, rage and flow through three movements of "Flux", starting at the "Source" and ending in an "Estuary"; awesome.

Recorded at the 2014 Ad Libitum Festival in Warsaw, pianist and composer Agusti Fernandez was invited to perform four concerts in celebration of his 60th birthday, choosing his working trio Aurora for once concert, a solo performance of "El Laberint de la Memoria", his electroacoustic Thunder trio, and a large ensemble conduction: "River, Tiger Fire".

Slovenian percussionist Zlatko Kaucic reinforces the title of his "Diversity" box set over 5 CDs in a variety of solo, duo, trio and quartet setting, including some of the UK & Europe's finest improvisers--Evan Parker, Agusti Fernandez, Lotte Anker, Artur Majewski, Rafal Mazur, Phil Minton, and Johannes Bauer--an excellent example of his wide-ranging work as an improviser.

A unique freely improvised sax and bass duo from Angles leader Martin Kuchen on alto and sopranino saxophones, and Rafal Mazur on acoustic bass guitar, recording live at BAZA Club in Krakow, Poland in 2017 they perform the two part "Baza", initiating with mastery and determination, morphing to more meditative playing, and ending with impressive assertion.

Splatter's 3rd CD resulted from a meeting between the London-based quartet Splatter (Noel Taylor-clarinet; Anna Kaluza-sax; Tom Greenhalgh-drums; Pedro Velasco-electric guitar) and Polish bassist Rafal Mazur after their successful collaboration at Cafe Oto in 2010.

With links to Foton Quartet, Rob Mazurek, Nicole Mitchell, Keith Rowe, Kevin Drumm, Matt Bauder, &c, the Polish & German quartet of Anna Kaluza (sax), Artur Majewski (trumpet), Rafal Mazur (guitar) & Kuba Suchar (drums) perform a perfect blend of bebop, free forms, west coast jazz and free improvisation.
