Any of his recordings on ECM (there are two or three more in addition to the ones I own) will be good. Soul of Things is the only other one that uses the same group configuration as Suspended Night, though, so be warned. From the Green Hill is really interesting, IMO, because it matches Stanko with multi-reedist John Surman (the secret weapon in the ECM arsenal) and Argentinian bandoneon ninja Dino Saluzzi for a texturally delicious sonic exploration.
I would love it if Stanko did a record with Kenny Wheeler, who is his complete opposite as a trumpeter in terms of tone yet seems like he's working from a similar place as a player.
