get a drummer. there are lots of drummers. just get one.
20 some years ago, I was fronting, singing, and playing harp for a local SoCal 4 piece band that had a "less then reliable" drummer. He was very talented. But a PITA to deal with.
(I'll be clear in saying that not only was he unreliable but both he and his wife/girlfriend [how they referred to each other depended on how they were getting along at the time] were extremely disrespectful to the other members of the band, including me. He let me know he didn't like my vocals, although I was the guy getting him gigs. To be fair, I'm not sure I'm a great blues singer.)
Sometimes I had to go pick him up, 30 miles one way. He once missed a gig, his wife/girlfriend calling at the last minute to say he wasn't coming because his truck wouldn't start.
We rocked without him. Because we had no choice. People still got up and danced because we all stepped it up.
Somehow he got a gig with a band that was touring Europe. As I said before, very talented.
When he got back, he called me and asked when WE had more gigs. I managed not to laugh.
Life is short. Working with people who are unreliable or not talented or hard to get along with is not worth it.
I've worked with a gazillion (round number) of talented drummers since then.
You'll find one. Or turn into an acoustic trio. Either is good.
