Momenta is Arguelles' return to a big band setting, and is the culmination of composing, rehearsing and performing with the Frankfurt Radio Big Band where he now works. Recorded live in concert, Momenta is a collection of new arrangements of Arguelles compositions, both old and new, plus two new compositions specifically for this project. Arguelles' ever-changing formats have produced acclaimed trio, quartet, octet and solo recordings, yet his relationship with big bands is a long-standing one. A member of the European Youth Jazz Orchestra, a founding member of the mid 80's maverick ensemble, Loose Tubes, he has worked with large groups led by Django Bates, Chris McGregor's Brotherhood of Breath and Kenny Wheeler's Big Band for 20 years. Arguelles has written for the Hamburg Radio Big Band, Scottish National Jazz Orchestra, and Royal Academy of Music Jazz Orchestra. He feels this project is an extension of his earlier arrangements.
