Situation: A local band with one of those names that you just know has to be improved on or replaced some day. They claim that their awesome permanent bassist needs a few months to do something important (e.g. final semester of final year in school) but the band still has hopes of continuing to perform during those months. They want a gigs-ready bassist right now. They send you a link to about an album's worth of material - all differing in sound quality and volume, some new, some old, some covers - and do not specify (even when asked) which tunes they'd like you to learn. It's an all-originals band that hates the pigeon-holing of stating their genre. Instead, they provide a list of influences in multiple genres. Task: They just want somebody to blend in to the band, playing all of their material on the bass in gig-ready mode right away. You show up to their rehearsal space. Everybody has to wait awhile for 1 or 2 of the band to show up, then tune up and get ready. Just when it seems time for the BL to call a tune and everybody play, they all stand in a circle passing something around and invite you to have a hoot. You know: the bonding ritual. Action: The BL calls an original tune. You had not even a hint ever that they might have wanted you to listen to and maybe learn this one (or any other) in advance. There are no charts. Nobody names any of the chords - not even the key. Not even a whisper about the tempo or the structure. Everybody starts playing. You completely improvise it all by ear. Maybe for the next one, you'll have the preparatory benefit of having played this one with them. Four or five original tunes are played by all, you expected to play the bass and make their songs sound and feel right. Result: Everybody thanks everybody else. You're never invited back.
